In April 1999, a $433 million Air Force rocket inexplicably malfunctioned almost immediately after liftoff, causing the permanent loss of an $800 million military communications satellite. This $1.2 billion disaster remains one of the costliest accidents in human history.

You might wonder if scientists ever found out what caused this misfiring. They sure did! And the answer is a software bug.

This accident alone is a testament to the importance of software testing.

Although you can probably deduce the software testing definition, let’s also review it together.

So, what is software testing?

Software testing refers to running a software program before putting it on the market to determine whether it behaves as expected and displays no defects.

While testing itself isn’t free, these expenses are cost-effective compared to potential money loss resulting from software failure. And this is just one of the benefits of this process. Others include improving performance, preventing human and equipment loss, and increasing stakeholder confidence.

Now that you understand why software testing is such a big deal, let’s inspect this process in more detail.

Software Testing Fundamentals

We’ll start with the basics – what are the fundamentals of testing in software engineering? In other words, what exactly is its end goal, and which principles underlie it?

Regarding the objectives of software testing, there are three distinct ones aiming to answer crucial questions about the software.

• Verification and validation. Does the software meet all the necessary requirements? And does it satisfy the end customer?
• Defects and errors identification. Does the software have any defects or errors? What is their scope and impact? And did they cause related issues?
• Software quality assurance. Is the software performing at optimal levels? Can the software engineering process be further optimized?

As for principles of software testing, there are seven of them, and they go as follows:

1. Testing shows the presence of defects. With everything we’ve written about software testing, this sounds like a given. But this principle emphasizes that testing can only confirm the presence of defects. It can’t confirm their absence. So, even if no flaws are found, it doesn’t mean the system has none.
2. Exhaustive testing is impossible. Given how vital software testing is, this process should ideally test all the possible scenarios to confirm the program is defect-free without a shadow of a doubt. Unfortunately, this is impossible to achieve in practice. There’s simply not enough time, money, or space to conduct such testing. Instead, test analysts can only base the testing amount on risk assessment. In other words, they’ll primarily test elements that are most likely to fail.
3. Testing should start as early as possible. Catching defects in the early stages of software development makes all the difference for the final product. It also saves lots of money in the process. For this reason, software testing should start from the moment its requirements are defined.
4. Most defects are within a small number of modules. This principle, known as defect clustering, follows the Pareto principle or the 80/20 rule. The rule states that approximately 80% of issues can be found in 20% of modules.
5. Repetitive software testing is useless. Known as the Pesticide Paradox, this principle warns that conducting the same tests to discover new defects is a losing endeavor. Like insects become resistant to a repeatedly used pesticide mix, the tested software will become “immune” to the same tests.
6. Testing is context-dependent. The same set of tests can rarely be used on two separate software programs. You’ll need to switch testing techniques, methodologies, and approaches based on the program’s application.
7. The software program isn’t necessarily usable, even without defects. This principle is known as the absence of errors fallacy. Just because a system is error-free doesn’t mean it meets the customer’s business needs. In software testing objectives, software validation is as important as verification.

Types of Software Testing

There are dozens (if not hundreds) types of testing in software engineering. Of course, not all of these tests apply to all systems. Choosing the suitable types of testing in software testing boils down to your project’s nature and scope.

All of these testing types can be broadly classified into three categories.

Functional Testing

Functional software testing types examine the system to ensure it performs in accordance with the pre-determined functional requirements. We’ll explain each of these types using e-commerce as an example.

• Unit Testing – Checking whether each software unit (the smallest system component that can be tested) performs as expected. (Does the “Add to Cart” button work?)
• Integration Testing – Ensuring that all software components interact correctly within the system. (Is the product catalog seamlessly integrated with the shopping cart?)
• System Testing – Verifying that a system produces the desired output. (Can you complete a purchase?)
• Acceptance Testing – Ensuring that the entire system meets the end users’ needs. (Is all the information accurate and easy to access?)

Non-Functional Testing

Non-functional types of testing in software engineering deal with the general characteristics of a system beyond its functionality. Let’s go through the most common non-functional tests, continuing the e-commerce analogy.

• Performance Testing – Evaluating how a system performs under a specific workload. (Can the e-commerce shop handle a massive spike in traffic without crashing?)
• Usability Testing – Checking the customer’s ability to use the system effectively. (How quickly can you check out?)
• Security Testing – Identifying the system’s security vulnerabilities. (Will sensitive credit card information be stored securely?)
• Compatibility Testing – Verifying if the system can run on different platforms and devices. (Can you complete a purchase using your mobile phone?)
• Localization Testing – Checking the system’s behavior in different locations and regions. (Will time-sensitive discounts take time zones into account?)

Maintenance Testing

Maintenance testing takes place after the system has been produced. It checks whether (or how) the changes made to fix issues or add new features have affected the system.

• Regression Testing – Checking whether the changes have affected the system’s functionality. (Does the e-commerce shop work seamlessly after integrating a new payment gateway?)
• Smoke Testing – Verifying the system’s basic functionality before conducting more extensive (and expensive!) tests. (Can the new product be added to the cart?)
• Sanity Testing – Determining whether the new functionality operates as expected. (Does the new search filter select products adequately?)

Levels of Software Testing

Software testing isn’t done all at once. There are levels to it. Four, to be exact. Each level contains different types of tests, grouped by their position in the software development process.

Read about the four levels of testing in software testing here.

Level 1: Unit Testing

Unit testing helps developers determine whether individual system components (or units) work properly. Since it takes place at the lowest level, this testing sets the tone for the rest of the software development process.

This testing plays a crucial role in test-driven development (TDD). In this methodology, developers perform test cases first and worry about writing the code for software development later.

Level 2: Integration Testing

Integration testing focuses on the software’s inner workings, checking how different units and components interact. After all, you can’t test the system as a whole if it isn’t coherent from the start.

During this phase, testers use two approaches to integration testing: top-down (starting with the highest-level units) and bottom-up (integrating the lowest-level units first).

Level 3: System Testing

After integration testing, the system can now be evaluated as a whole. And that’s exactly what system testing does.

System testing methods are usually classified as white-box or black-box testing. The primary difference is whether the testers are familiar with the system’s internal code structure. In white-box testing, they are.

Level 4: Acceptance Testing

Acceptance testing determines whether the system delivers on its promises. Two groups are usually tasked with acceptance testing: quality assessment experts (alpha testing before the software launches) and a limited number of users (beta testing in a real-time environment).

Software Testing Process

Although some variations might exist, the software testing process typically follows the same pattern.

Step 1: Planning the Test

This step entails developing the following:

• Test strategy for outlining testing approaches
• Test plan for detailing testing objectives, priorities, and processes
• Test estimation for calculating the time and resources needed to complete the testing process

Step 2: Designing the Test

In the design phase, testers create the following:

• Test scenarios (hypothetical situations used to test the system)
• Test cases (instructions on how the system should be tested)
• Test data (set of values used to test the system)

Step 3: Executing the Test

Text execution refers to performing (and monitoring) the planned and designed tests. This phase begins with setting up the test environment and ends with writing detailed reports on the findings.

Step 4: Closing the Test

After completing the testing, testers generate relevant metrics and create a summary report on their efforts. At this point, they have enough information to determine whether the tested software is ready to be released.

High-Quality Testing for High-Quality Software

Think of different types of software testing as individual pieces of a puzzle that come together to form a beautiful picture. Performing software testing hierarchically (from Level 1 to Level 4) ensures no stone is left unturned, and the tested software won’t let anyone down.

With this in mind, it’s easy to conclude that you should only attempt software development projects if you implement effective software testing practices first.

Acquire Computer Science Knowledge Effectively

Although books don’t offer practical knowledge, they can be invaluable allies in setting a great theoretical foundation. By carefully choosing the best books and putting effort into developing your skills, you’ll become a pro in a jiff.

Computers are already ubiquitous in the workplace, with the constantly-evolving concept of cloud computing becoming so popular that Tech Jury says 90% of businesses were in the cloud (in some form) in 2022. All of those systems need maintenance and software, requiring people who are dab-hands with keyboards at their fingertips to build networks, analyze data, and develop software.

Enter computer scientists.

By studying computer science, you open yourself up to a branching career path that could take you into almost any sort of business. But before that, you need to know the answer to a simple question – “Is BSc Computer Science a good course?”

Understanding BSc Computer Science

Think of a BSc in Computer Science as though it’s a buffet, with every topic covered being a different dish. You’ll get a taste of everything that’s on offer in the computing field, with your later educational (and career) decisions being based on the dish (i.e., the topic) that you like best. Among those topics and study areas are the following:

• Networks and Computer Systems – Taking a more hardware-oriented focus (though software plays a part), this topic covers how to connect computers so they can interact with one another.
• Programming – The language of computers is one you’ll need to learn how to speak if you want to develop software or websites. You’ll discover that there are a lot of languages to choose from, each with its own specific uses.
• Artificial Intelligence (AI) – As one of the fastest-growing fields in computing (Statista anticipates growth from $100 billion in 2021 to almost $2 trillion by 2030), AI is already becoming essential in business. You’ll learn the concepts that govern AI, such as machine learning and neural networks.
• Network Security – Every advancement in computer science brings with it malicious parties who wish to use (or subvert) that advancement to their own ends. Computer science courses teach the foundational aspects of network security, setting the stage for later specialization.

Moving beyond what you study (and the above isn’t an exhaustive list of topics), how long you spend on earning your BSc in Computer Science is another key deciding factor. Most traditional universities offer three-year courses, extending to four years if you take an internship or in-course work. The newer breed of online universities offer more flexibility, with some fast-track courses taking as little as two years, while others offer a more free-form version of study that lets you move at your own pace. With the latter, you could take several more years to complete your degree, though you’ll be able to fit your studies around work and family more easily than you would with a full-time course.

Benefits of BSc Computer Science

Assuming you’re willing to place the time (and monetary) investment into a BSc in Computer Science, there are three core benefits you’ll get from the course.

1 – Acquire In-Demand Skills and Knowledge

The basics you learn are in demand in most companies, with many offering additional training and tuition to help you build beyond the basics to become a specialist. Key areas of interest for employers include:

• Programming – Those who can speak the language that lies behind software are always in demand, with programmers earning an average hourly rate of $33.10, according to Indeed. Salary expectations climb as you move through the ranks, with senior software engineers capable of earning in the early six figures.
• Data Structures and Algorithms – Problem solvers are popular in any business. The knowledge of algorithms you develop when studying computer science allows you to create code (almost like a set of steps) that’s designed to solve problems. The same applies to data structures, which focus on the locations and methods used to keep data organized.
• Computer Networks and Security – Even a small office has a network of computers, laptops, smart devices, printers, and servers that all need to communicate with one another. Computer scientists enable that communication, and keep the “conversations” machines have with each other shielded from intruding eyes.

2 – Versatility and Adaptability in the Job Market

Computer science graduates are like the chameleons of the job market. They have so much foundational knowledge in an array of subjects that they’re well-placed to be “Jacks of all trades” as general computer experts. Plus, the base they have can be built from, setting the stage for them to specialize in specific areas of computing based on their preferences.

We’ll dig into some specific roles you could take (along with their salaries) in the next section of the article.

3 – Opportunities for Further Education and Specialization

You’re already part way down the road to computer science mastery once you have your BSc, so why stop there? The opportunity exists for further education and specialization, which could open the door to further career opportunities:

• Masters and Ph.D. Programs – A Master’s degree in computer science (or a related subject) is the next logical educational step once you have your BSc. You’ll build on what you’ve already learned, in addition to having a chance to specialize in your thesis. PhD programs aren’t immediately open (you’ll need your Master’s first) but they give you a chance to delve into subject-specific research and could set you up for a career in teaching computer science.
• Professional Certifications – If you prefer the less formal educational route, professional certifications enable you to study at your own pace and give you handy pieces of paper you can use to prove your skills. Great examples include Cisco’s CCIE program and CompTIA’s range of certifications.

Job Prospects and Career Opportunities

Building on the previous mention about your chameleon-like ability to get jobs in multiple fields, you need to know is BSc in Computer Science good for the career-focused student. These are the roles you can get (with salary data from Indeed).

Software Development and Engineering

Rather than being the person who uses software, you can be the person who forms and puts together the building blocks that make the software tick. Software developers and engineers use their coding skills to create the next great apps, websites, computer games, and anything else that needs a computer or mobile device to run.

Average Salary – $114,470

Data Analysis and Data Science

Data, data everywhere, and not a drop to drink. That little spin on the classic “lost at sea” phrase tells you everything you need to know about how many companies feel in the Big Data world. They’re collecting tons of data but don’t know how to organize what they have or extract useful information from it. Data analysts and scientists solve that problem.

Average Salary (Data Analyst) – $74,570

Average Salary (Data Scientist) – $129,574

Cybersecurity and Network Administration

There’s a never-ending battle being waged between network administrators and hackers, with each trying to stay one step ahead of the other. Cyberattacks are on the rise, with Security Magazine pointing out that attacks around the globe increased by 38% in 2022. That means there’s always demand for cybersecurity specialists.

Average Salary – $107,063

Research and Academia

Rather than using your skills to benefit private enterprises, you could be responsible for the next generation of computer scientists. The academic path is a noble one, though not always the most profitable, and it affords you the chance to research the subjects you’re passionate about. The level you reach in academia depends on your own academic accomplishments, with a BSc usually being enough for school-level teaching. You’ll need a Master’s or Ph.D. to go into further education or complex research.

Average Salary (Computing Teacher) – $26.79 per hour

Entrepreneurship and Freelance Opportunities

Why restrict yourself to a single company when you could build your own or spread your scientific seeds wide by becoming a freelancer? More control over your destiny is the biggest benefit of this career path, though there’s a more “sink or swim” mentality. Those who hit it big with a great business idea can hit it really big, but there are plenty of failed computing businesses on the entrepreneurial road.

Average Salary – It all depends on what you do and how well you do it

Factors to Consider When Evaluating the Worth of BSc Computer Science

If you’re still asking “Is BSc Computer Science a good course?” the answer is a definite “yes.” But there are some factors to consider before you commit to several years of computing studies:

• Personal Interests and Aptitude – Success in any area of study requires a passion for your subject and a certain amount of talent in the field. If you’re missing one (or both) of these for computer science then a BSc may not be for you.
• Job Market Trends – It’s very possible to make a six-figure salary as a computer scientist, though specialization is often needed to hit the highest figures. Still, it’s worth keeping an eye on what’s happening with the job market to ensure you’re studying toward a future role.
• Return on Investment – Undergraduate programs can cost anywhere between $15,000 and $85,000, so you need to feel confident that a computer science course is the right one for your future career. Otherwise, you’re left with a massive hole in your bank balance that you need to fill with student loan repayments.
• Job Satisfaction – Working yourself into the ground is never a good thing. You need to feel confident that you’ll achieve the appropriate balance between your work, personal, and family lives.

Comparing BSc Computer Science With Other Courses

A BSc in Computer Science is far from your only choice if you’re interested in delving into computers. Here are three alternatives to consider.

BSc Information Technology

Though an IT degree covers some of the same ground as a computer science one (especially when it comes to computer networks), you’ll trade theoretical knowledge for practical application. Expect to do a lot of work with databases and basic software, with some coding along the way.

BSc Data Science

As a more specialized course, a BSc in Data Science sees you delving deeper into the math and statistics behind computational systems. You’ll learn how to analyze data and may get a better grip on emerging tech, such as machine learning, than you would with a computer science degree.

Bachelor of Engineering (Computer Science)

A bachelor of engineering takes a more hardware-centric focus than a BSc, with this course teaching more about the principles of electrical engineering and how our computing devices actually work. There are still software components, and you’ll touch on similar subjects to a BSc, but you’ll get more practical experience with this course.

Is a BSc in Computer Science Good for You?

The most important question to ask isn’t “Is BSc Computer Science a good course,” but rather is it the right course for you? Your career goals, coupled with your desire (or lack thereof) to invest your time and money into the degree, may be the main deciding factors.

As with any course, ask yourself what the ultimate benefit is to you and weigh up your options (remembering that there are several types of computing degrees) to make the right choice.

According to Data USA, degrees in the business field are among the most popular in the United States, with 840,116 degrees in this field alone being awarded in 2020. You went down the commerce route (meaning you have a grasp of business administration, accounting, and applied economics) and now you’re interested in practical applications of your knowledge.

With your commerce degree firmly under your belt, you may feel like a ship without a rudder – aimless and having no idea what direction to go. Happily, the tech field is ready and waiting for you, as a career in computer sciences may await. Here, we ask, “can a commerce student do BSc Computer Science?” The answer may surprise you, especially if you’re worried that a computer science degree’s eligibility requirements are outside the scope of what you learned in your commerce studies.

Background on Commerce and Computer Science

On the surface, commerce and computer science may seem like they go together as well as peanut butter and granite. But if you dig a little deeper into the scope of each subject, you start to realize that there’s more crossover than there first appears:

• Commerce – A degree in commerce gives you a firm grasp of the numbers that lie behind the scenes in a business, with banking, economics, and accounting all falling under your developing areas of expertise. Analytics is also a key part of these courses (especially in the research and data analyst fields), which is where we see some crossover with computer science.
• Computer Science – If commerce is all about the behind-the-scenes numbers in business, computer science handles what goes on under the hood in computing. Software development, data modeling, and analysis all fall under the computer science graduate’s remit, with the ability to pore through data to come to conclusions being essential to this technical subject.

It’s in the analysis that we start to see similarities between commerce and computer science emerge. Yes, commerce focuses more on the numbers behind businesses (and wider economic trends), but the ability to understand the data presented and report on what you see has applications in the computer science field. There’s not a direct crossover, as computer science will require you to learn the “language” in which computers speak, but they are many soft skills you develop in a commerce degree that apply to computer science.

Eligibility for BSc Computer Science

The key questions to ask when considering the issue of whether can commerce student do BSc Computer Science split into two categories:

• The general eligibility requirements to study a BSc in computer science
• Specific requirements that apply to commerce students

Eligibility Criteria for BSc Computer Science

BSc Computer Science degrees don’t require a great deal of computer know-how (though it helps), instead focusing on your grasp of mathematics. Requirements include the following:

• A high school diploma (or your country’s equivalent) that shows solid performance in mathematical subjects.
  • Some degrees require you to achieve a specific Grade Point Average (GPA), though the specific GPA varies depending on where you apply.
• A high level of English proficiency, which can be measured using one (or both) of the following tests:
  • IELTS – Get a minimum score between 6.0 and 7.0
  • TOEFL – Get a minimum score between 90 and 100

Beyond these educational requirements, international students may need to submit copies of their passport and Visa, alongside certified academic transcripts to show they’ve achieved their country’s equivalents of the above grades. Not all courses require this of international students, with some online universities focusing more on your academic skills and less on your country of origin.

In terms of entrance exams, some colleges enforce computer science-specific exams (such as the CUET or CUCET), while others use NPATS or similar, more general exams, to determine proficiency.

Eligibility Criteria for Commerce Students

You may be standing at the starting line of your educational journey, meaning you’ve not yet applied to start your degree in commerce. First, congratulations on thinking so far ahead that you’re wondering “Can a commerce student do BSc Computer Science?” And second, you need to know what high school subjects help you get onto this degree path.

Commerce is a form of business degree, meaning any high school subjects that apply to the economic world help. Subjects like math, finance, economics, and foreign languages are obvious choices. The likes of marketing and computer applications also help (with the latter also laying some groundwork for your later computer science studies.

Much like computer science, you’ll likely have to take an entrance exam when applying to study commerce at most universities. The CSEET, CUET, and SET are common choices, with the first of these exams focusing specifically on those who study commerce to work as company secretaries.

The Possibility of Flexible Eligibility Criteria

Not all colleges require you to take entrance exams, with some even using broader strokes for their eligibility requirements to the point where they provide flexibility for both commerce and computer science students.

Colleges with open curriculums (such as Brown University and Hamilton College) offer more freedom in terms of what you study, with their entry requirements being more flexible as a result. Online institutions, such as the Open Institute of Technology (OPIT) may also offer more flexible entry criteria, sometimes allowing you to transfer credit from one course to another. That type of credit transfer may be ideal for you if you start a degree in commerce only to later decide to go down the computer science route.

Career Prospects for Commerce Students in Computer Science

When it comes to careers for those who hold computer science degrees, the obvious heavy-hitters are software and web development, IT management, and systems architecture. There are also exciting careers in the emerging AI fields that take full advantage of the technical skills you’ll develop as part of a BSc in computer science.

As for the career crossover between commerce and computer science, the key is to think about the skills that a commerce degree gives you that can apply in the computing field. Such skills include the following:

• Analytical Skills – Much like computer science, commerce is all about analyzing the data presented so you can report (and leverage) it for other purposes. Your ability to sit down and pore through the numbers will take you a long way in a computer-related role.
• Problem-Solving Skills – Closely linked to analytical skills, the ability to solve problems requires you to see the data at hand and come up with solutions while accounting for any restrictions presented. In creating commerce models, those restrictions may relate to budget and competencies, while computer science asks you to solve problems while taking system capabilities and limitations into account.
• Communication and Teamwork – Though often considered soft skills (as opposed to the “hard” technical skills you learn in a commerce degree), communication and teamwork are vital. If you need proof, try to work alone in any technical career and you’ll see why it’s so crucial to have these skills.

Potential Career Paths for Commerce Students with a BSc in Computer Science

With so much crossover potential between commerce and computer science, it’s clear that the answer to the question can a commerce student do BSc Computer Science is a resounding “yes.” And once you’ve completed your studies, several career paths await:

• Data Analyst – Reviewing data to find insights (be that into businesses or computer systems) are part of the remit for a data analyst. This role is all about problem-solving, which is a skill you’ll develop in abundance as a commerce and computer science student.
• Business Analyst – Take the ability to gather insights that is required of a data analyst and apply it specifically to areas of improvement in a business to become a business analyst. You’ll combine technical knowledge of a company’s inner workings with complex financial (and computational) models.
• IT Consultant – More computer science-centric than commerce-focused, IT consultants deal with the hows and whys of the computer networks businesses build. Your commerce skills will still come into play though, particularly when explaining how IT benefits businesses financially.
• Financial Technology Specialist – Combining the best of both worlds, this role combines the accounting skills you develop studying commerce with the technical ability needed to understand software and its functions.

Challenges and Considerations for Commerce Students

Though it’s possible for a commerce student to study (and succeed in) computer science, there are some challenges to consider.

The Technical Nature of Computer Science

As you learn the language of numbers in a commerce degree, so must you learn the language of machines when studying computer science. Getting to grips with the lingo (not to mention coding) can present a challenge to more business-minded students.

Balancing Your Workload

There’s an old saying that goes “Don’t burn the candle at both ends,” which is a warning not to pack too much onto your work plate. If you study commerce and computer science simultaneously, there’s a risk you may push yourself too far. Avoiding burnout requires finding the balance between your studies and personal time.

Networking and Practical Experience

As a commerce student, you understand that the world of business is as much about who you know as what you know. Finding the right people to take a chance on you, thus giving you practical experience, can be tough. But when armed with a pair of degrees in subjects that complement one another, you’re in a better position to build connections with people who can help you go far.

From Commerce to Computing – Is It Right for You?

So, can a commerce student do BSc Computer Science?

The answer isn’t just “yes,” but that it’s actually a great direction to go. Where a commerce degree equips you with a nice mix of technical knowledge and soft skills, a computer science course gives you even more practical knowledge that allows you to enter more specialized fields. However, your interest in each subject plays a role, as your ability (and passion) for studying hinges on your desire to dig into the more technical world of computing.

Assuming you have a genuine interest (and meet the appropriate eligibility criteria), supplementing your commerce studies with computer science can open up many career paths.

Do you tend to get all technical about how computers work? Or, do you prefer to put your thinking cap on and dig deep into theory and research?

These questions matter because they can help you choose between BCA and BSc Computer Science. One focuses on practical knowledge, while the other explores the nitty-gritty behind technical concepts.

In this BCA vs. BSc computer science: which is better guide, we’ll provide detailed information about the two courses and help point you in the right direction.

Land the Best Jobs in the Industry

If you were wondering, “Can I get a job after BSc Computer Science?” the answer is absolutely! Computer scientists are in high demand, and with a BSc Computer Science degree in your hands, you can drive your career in the desired direction.

Besides your degree, don’t forget about the not-so-secret ingredient in your recipe for success: constant improvement and development.

Data management is one of the biggest challenges for modern businesses. The more information that enters a company, the harder it is to stay on top of all of it. However, successful owners wouldn’t be where they are if they threw in the towel. They go out of their way to find a solution to solve this problem.

Enter database management systems (DBMSs). A database management system is a program that allows you to store and organize information more easily.

The importance of a DBMS can’t be overstressed. It can be a light at the end of the tunnel for many organizations. For example, it helps optimize performance across the board, increase productivity, and reduce cybersecurity risks.

This article will take a closer look at database management systems. We’ll explore the concept of database management systems, the basic principles of database management systems, and other essential aspects.

Types of Database Management Systems

We’ve defined a “database management system.” Next, it only seems natural to kick this introduction to database systems off with an examination of the types of software that address this issue.

Hierarchical DBMS

Much of today’s world is about hierarchies. There are hierarchies in your family, in the sequence of actions when starting a car, and in many other aspects of life.

Hierarchy also permeates data in the form of hierarchical database management systems. These solutions typically use tree-like formats to organize data from top to bottom or from bottom to top. Each approach is characterized by “parent and children” information.

Regardless of the approach, one thing’s for sure – children can’t have multiple parents, but parents can have multiple children. The same rings true for data points, meaning they can’t have three or four “parents.”

Network DBMS

A network database management system is similar to the hierarchical type. However, the two aren’t carbon copies of each other. The biggest difference is that “child” data can have more “parents” in a network DBMS. It allows IT professionals to accommodate complex information clusters.

Relational DBMS

The DBMS market is expected to soar to over $150 billion by 2030. You might think that such a valuable industry is only home to advanced solutions, but that’s not quite true.

Relational database management systems have a relatively simple premise – organizing data in columns and rows. In this respect, they work like Microsoft Excel and some other basic programs.

Object-Oriented DBMS

Object-oriented models use, well, models. They store all sorts of user information in structures known as classes.

NoSQL DBMS

Google and other internet giants process billions of terabytes of data daily. They need a robust database management solution that lets them stay on top of such vast quantities.

Salvation comes in the form of NoSQL. This system is incredibly scalable and flexible because it doesn’t require data set combinations. Therefore, it’s perfect for large-scale, big-data operations.

NewSQL DBMS

Finding a perfect database management system sometimes feel like looking for a needle in a haystack. However, it becomes an easier task if you have clear priorities. If you want a platform that combines the scalability of NoSQL and ACID compliance, check out NewSQL. It offers unrivaled data integrity, which also increases security.

Components of a Database Management System

Our introduction to database management systems has covered the DBMS definition, which answers the question “What is DBMS?” We’ve also explored various types of database management systems. Now let’s delve into the components of these solutions.

Database Engine

The engine of a database is like the foundation of a house. This core element processes every information and query that enters the system.

Data Definition Language (DDL)

You can’t have a house without a foundation, and you can’t build one without a roof either. That’s how important a DDL is to a database. It ensures pieces of information can interact with each other and facilitates data retrieval. It also allows you to modify certain parts of the structure.

Data Manipulation Language (DML)

The four basic operations of a database system are create, read, update, and delete. The DML is responsible for executing these tasks.

Data Control Language (DCL)

You’ve constructed the foundation of your house, but you need to keep intruders from entering with a door. A database also needs a door, and a DCL is the best solution. It determines who can access your system.

Transaction Management

Internal transactions are common in all databases. A transaction management system controls them to ensure ACID compliance.

Database Recovery

Database failure is like a devastating house fire that destroys everything – you don’t give up and do nothing. Instead, you rebuild the structure.

Database recovery works the same. It’s a set of tools that enables you to reconstruct your database from scratch.

Applications of Database Management Systems

A DBMS, especially a DBMS full form, has a wide range of applications. The technology is as versatile as a hybrid vehicle, meaning you can use it practically anywhere. Here’s where you can regularly find database management systems:

• Banking and finance – Financial institutions need a fully functional DBMS to process loan, account, and deposit information.
• Healthcare – Hospitals and other healthcare organizations have numerous patient records. Managing them is much easier with a DBMS.
• Telecommunications – Have you ever thought about how your cell phone carrier maintains your information and that of millions of others? The answer lies in a DBMS. It stores phone records and bills, among other crucial information.
• Education – If you’re a student, your school or college needs to keep track of your attendance, marks, and assignments. The best way to do so is to set up a database management system.
• E-commerce – How do various e-commerce platforms streamline your shopping experience? They implement a DBMS to recommend products and services, record your habits, and memorize your payment information.
• Government and public sector – The applications of database management systems for government are virtually endless. These include national security, voter registration, and social security.

Principles of Database Management Systems

Although there are numerous database management systems, they take the same approach to storing and organizing information. Each platform needs to follow these principles:

• Data independence – This principle is pretty self-explanatory. If you can change a piece of information in your database, your structure is independent.
• Data consistency – You might store the same folder in different locations on your computer for backup purposes. You should be able to do the same with data in your database without altering the information. If the data appears differently in various locations, it’s inconsistent.
• Data integrity – The last thing you want is to work with corrupt information. It can affect the rest of the database and grant unauthorized personnel access to your data. But none of this is an issue if your system has high data integrity.
• Data security – Data security is like home security – you don’t want invaders to steal your possessions. On the same note, you don’t want cyber criminals to tap into the system and compromise sensitive information.
• Data recovery – If your system shuts down unexpectedly, you need to be able to retrieve your information in its last saved state.
• Concurrency control – A database management system isn’t designed to perform just one operation. It can run numerous tasks simultaneously, which is why you need concurrency control to manage the execution of those operations.

Examples of Popular Database Management Systems

Here are some of the most common database management systems:

• Oracle database – A relational system that comes in two versions: cloud and on-premises.
• Microsoft SQL server – Another relational program, which is built on the SQL architecture.
• MySQL – Companies with large databases use MySQL to organize and control massive amounts of information.
• PostgreSQL – This is an object-relational database that complies with the SQL environment.
• MongoDB – A scalable and flexible system with optimized indexing and queries.
• IBM Db2 – If you’re looking for a platform developed by a tech giant, IBM Db2 is a great choice. It’s perfect for real-time information analysis.

Notes and Basics of Database Management Systems

To wrap up the discussion about database systems, we’ll cover the basics of database management systems and database management system notes:

• Importance of data modeling – Just as you tidy up your room to find clothes more easily, you want to model data to retrieve information effortlessly. The process eliminates redundant details for easier management.
• Database normalization – Another great way to reduce errors in a DBMS is to perform database normalization. It allows for accurate modifications and helps improve your workflow.
• Indexing and query optimization – By indexing the data in your system, you decrease the information your queries need to analyze. In turn, this leads to higher database efficiency.
• Backup and recovery strategies – IT professionals must have sound backup and recovery strategies in place. They reduce downtime associated with information loss after shutdowns or errors.
• Database administration and maintenance – A database administrator should formulate the overall strategy for the entire system. It simplifies maintenance and lowers the risk of errors.

The Concept of DBMS Demystified

Much of cutting-edge technology is an enigma, but hopefully, that’s no longer the case with database management systems. Hierarchical, network, relational, and other systems are instrumental in organizing information and making it more accessible. The onus is on IT professionals to master each solution applicable to their industry to improve their company’s workflows.

Future trends may put extra emphasis on this need. As most databases migrate to the cloud and organizations prioritize cyber security, IT experts will need to adapt their approach to database management.
