Software Development Life Cycle (SDLC)

Software Development Life Cycle (SDLC)

Introduction

Application development has never been simple, and it will never be. Because the goal is to make application development as simple as possible, there are various types of websites and tools for application development available today; however, if we are talking about applications developed to meet the specific needs of clients, this method of application development will not suffice.

Smaller, simpler applications can be classified as such development. However, large and complex applications, of which there are many more today, necessitate a team of developers, better organization, and a more serious approach to the development itself.

The SDLC, or Software Development Life Cycle, is a set of specific steps that must be completed to develop successful and high-quality applications. The advantage of this approach is that each step represents a component of the application’s development, which can be further subdivided into smaller tasks for developers. This makes it easier to follow the software application’s development process. SDLC is also referred to as the software development process.

What is SDLC?

A process that initially solves a large number of problems is required for successful and high-quality application development. The most common issues are application development deadlines, quality, and application development costs.

SDLC’s goal is to create a high-quality application that meets all of the client’s requirements while staying within all application development deadlines and costs. Because the SDLC provides a detailed application development plan, which includes an assessment of the shortest time required for application development, it ensures that the application’s quality is high in the end and that the price remains within the appropriate range as initially agreed with the client. As a result, SDLC solves all of the most common problems encountered during professional application development.

SDLC is also a method or standard for evaluating and improving the application development process. IT companies use SDLC as part of their project management processes. Each step contributes to the efficiency of application development and thus aids the IT company in its implementation.

How does SDLC work?

One of the goals is to reduce application development time as much as possible. By dividing tasks into sections, all redundancy is eliminated, and there is little room for wasting time. As a result, a more accurate estimate for the final project deadline can be made, and the development speed is significantly increased.

At any time, the client can see how far the project has progressed and whether everything is going according to plan or if some changes are required. SDLC gives the IT company and the client complete control over the application development process from beginning to end.

To make all of this possible, the IT company must employ one of the SDLC’s software development methodologies. For software development, the Agile and Waterfall methodologies are most commonly used.

SDLC steps

The SDLC is typically divided into seven steps; however, depending on the project manager, the project may have fewer or more steps. SDLC should follow these seven steps:

  1. Planning
  2. Defining requirements
  3. Design and prototyping
  4. Software development
  5. Testing
  6. Deployment
  7. Maintenance

1. Planning

The most important phase is the planning phase, which is where everything starts. It is critical to get everything right during this phase so that the rest of the process runs as smoothly as possible.

A meeting with the client is scheduled to gather all of the information about what the client expects from the project. This stage encompasses all aspects of project and product management. Typically, information is gathered about who the end user will be and what the project’s overall goal will be. Typically, business analysts and project managers attend this meeting with the client.

During the planning phase, information is gathered not only from the client but also from all project stakeholders. A stakeholder is anyone who benefits from the project.

2. Defining requirements

The following step is to develop software requirements and get them approved by project stakeholders. To accomplish this, a Software Requirements Specification (SRS) document is created, which should include all of the requirements that will be developed.

The SRS document is used to determine the resources required to meet the project’s requirements and to estimate the cost. This phase determines not only what is required for the project, but also what is not.

3. Design and prototyping

The goal of this phase is to determine in detail how the project’s software application will function. All of the information gathered in the previous two phases is grouped. The platform and technologies to be used in the project have been decided. The user interface, or how the user will interact with the application, has been defined.

Following the selection of a platform and technology, the method of communication with other services, servers, and instances is defined. Depending on the project, consideration is given to how the protection will be implemented and what security measures are required to protect the software application.

During the design phase, a software application prototype is typically created. A prototype is an alpha version of an application that contains some basic functionality or design elements. A prototype is created to visually demonstrate the basic idea of how the application looks and functions to stakeholders. This is done to provide stakeholders with more detailed feedback, which will aid in future development. Without the prototype phase, creating the same application would take much more time, patience, and money because many things would have to be changed during the development phase. All of these issues can be resolved during the design phase.

4. Software development

Programming can begin during the software development phase. The number of developers may vary depending on the project’s complexity. Some projects can be completed by a single developer, while others may necessitate the collaboration of several developers.

The development team adheres to the design and focuses on coding. To track code changes, a central repository is established. An important first step in working in a team is to ensure that all team members have tool compatibility so that everyone is fully synchronized without any unnecessary deviations.

The SDLC’s longest phase is software development. Errors are fixed and problems that arise during development are resolved during this phase. Tasks are frequently delayed due to a variety of factors such as test results. The developer must wait for the test results before proceeding with development or corrections, and the software tester must wait for the developer to build a specific part before testing it. SDLC solves these problems so that the development team can work on other tasks during each wait to avoid wasting time.

5. Testing

The testing phase is becoming more prevalent in smaller software applications, as well as larger and more complex ones. Application testing is critical before making the application available to users because it ensures that the application will function as expected.

Depending on the requirements, testing can be either manual or automated. Various bugs or defects may be discovered during the testing phase, in which case developers are instructed to fix them so that the code remains clean and the application functions properly. The process is then repeated, with the developers submitting a new version of the application for testing until all of the tests are marked as successful.

Testing eliminates many problems that users might encounter, increasing user satisfaction and thus making the application more easily accepted by users.

6. Deployment

This is the stage at which the application is officially made available to users. The application is ready for deployment once the testing phase is completed successfully. The deployment phase can be simple or complex, depending on the application’s purpose and the client’s needs. If the deployment is done from the beginning, it can be simple. However, if it is an upgrade of some existing systems, it can be complex and time-consuming.

7. Maintenance

Following the completion of the deployment phase, the maintenance phase begins. The application is regularly used by the user during this phase, and its performance is monitored. There are rare cases where all bugs are discovered during the testing phase, which is why the maintenance phase is important because it allows users to discover new bugs and provide feedback. They are then removed, and a new patched version of the application is made available.

What software development methodologies are used in SDLC?

SDLC employs many methodologies. These methodologies are frequently referred to as Software Development Process Models. Each model includes several steps that facilitate the software development process.

The following are some of the most popular SDLC models or methodologies:

  • Agile Model
  • Waterfall Model
  • V Model
  • Lean Model
  • Spiral Model
  • Iterative Model
  • DevOps Model
  • Big Bang Model

What are the benefits of SDLC?

The most significant advantage of the SDLC is that it establishes a common goal for all participants, while each participant understands exactly what his role is in achieving the final goal. It enables participants to collaborate to create a plan, divide roles, and begin implementing the plan in such a way that each participant’s work is maximized. SDLC can be adapted to any situation where the software needs to be developed due to the various software development methodologies.

Conclusion

Without the SDLC, the software development process would be less disciplined, significantly more complex, prone to errors, and fail to communicate effectively among participants.

When it comes to professional software development, all participants must have a clear understanding of what is being done and when it is being done. The role hierarchy within the SDLC is also important. Although all members participate in discussions, final decisions are made by members with higher hierarchical roles. The SDLC provides the client with real-time visibility into the status of the project.

As time passes, the SDLC improves and adopts more modern models, such as DevOps. This is a trend that will almost certainly continue, as it is both normal and necessary to keep up with modern software application development.

What is a Content Management System (CMS)?

What is a Content Management System (CMS)?

Introduction

CMS is an acronym that is commonly used on the Internet when creating websites. This acronym’s popularity is not by chance, and it has numerous advantages. CMS is an abbreviation for Content Management Systems, and it plays an important role in business development.

It is important to note right away that nearly 80 million websites use some form of CMS.

In this post, we will go over several CMS-related topics in depth:

  • What is CMS, exactly?
  • How does the CMS work?
  • What does a CMS consist of?
  • What are the popular CMS platforms?
  • What types of websites can be built with CMS?
  • What are the main advantages of the CMS platform?

What is a Content Management System (CMS)?

A Content Management System (CMS) is a software platform designed to provide a potential solution to certain issues that may arise during the development of a website.

  • The process of creating a website can be demanding and difficult, and it is necessary to set aside a significant amount of time for the website to be completed successfully and on time.
  • Depending on the requirements for website development, the number of developers may vary. The more extensive the requirements and the shorter the development time, the higher the number of developers and thus the cost of creating such a website.
  • One of the most important factors here is expertise. A website is insufficient if it is not designed for non-professional users.

All of the problems mentioned above are easily solved by the CMS platform.

How does the Content Management System work?

When creating a traditional website, the developer would have to upload all of the necessary files to the server and configure the server to download and display the appropriate files as needed. In such a case, the developer has his hands full, and the process can take longer or shorter depending on the developer’s experience and the hosting platform.

CMS, on the other hand, eliminates the need to upload code files because such files are already included. What is required is to populate those files with the necessary information. All of this is possible with the dashboard. Using the dashboard to enter content into files looks like entering plain text, and most settings are done with a mouse click.

Media files, such as images, video clips, or documents, are frequently required to be uploaded.

Developers can, of course, experiment with a CMS’s source files if it is an open-source project. There is a lot of freedom in customizing the CMS platform, but there are some limitations in terms of website development from the start.

What does a Content Management System consist of?

CMS, like web applications, is divided into two parts: front-end and back-end.

The front-end is the part of the website that allows the user to manage it through the dashboard. The front-end also includes the design of the website that end users or clients see.

The back-end is the part of the application that runs in the background and is responsible for storing data in the database, manipulating data with code, and displaying data. The back-end section is primarily concerned with the CMS system’s functionality.

Because the CMS system uses both the front-end and the back-end equally, we can say that CMS is a complete software solution that is widely accepted.

For website development, many CMS platforms rely on plugins and themes. A plugin is a small application that performs or assists in the performance of a specific task. Plugins are CMS extensions that aid in website development. There are both free and paid plugins.

Themes can also be very useful during the development of a website. Themes simplify website development by providing ready-made templates that look great with minimal changes. There are both free and paid premium themes available. Free themes typically provide only the most basic elements of the template, whereas premium themes provide many additional options to make the website look even better.

Because CMS is such a popular software solution, there are a plethora of CMS platforms that are popular and widely used in the domain of website creation.

For a long time, there have been three leading CMS platforms, one of which stands out as the most popular and best. WordPress, Drupal, and Joomla are the most popular CMS platforms in terms of the number of websites and users.

When it comes to CMS platforms, WordPress is the clear winner. It is widely regarded as the best and most popular CMS platform in the world. WordPress powers nearly half of all websites on the planet.

Drupal and Joomla take up much less market space for website development, but because they have been around for a long time, they have a good reputation as well as many useful ready-made modules that can be used for website development.

WordPress, Drupal, and Joomla are long-standing CMS platforms that perform similarly, but there are also more modern CMS platforms.

Squarespace, Wix, and Weebly are examples of more recent CMS platforms. The difference is that such CMS platforms give average users even more support for website development and allow for a drag-and-drop approach to creation. In addition to being simpler to use, they provide a comprehensive website development solution that includes additional services such as hosting.

For older CMS platforms such as WordPress, Drupal, and Joomla, specific professional knowledge is still required to cover the entire development of the website from start to finish. In any case, average users will require the assistance of a developer. That problem is solved by more modern CMS platforms, which take over that part, leaving the user with only the process of creating a website.

Other CMS platforms include Magento, Webflow, TYPO3, Contentful, HubSpot, Shopify, and numerous others. We have only included the most popular CMS platforms in this section. However, others serve a similar purpose or function slightly differently.

What types of websites can be created using a Content Management System?

CMS platforms today can include several different types of websites and be more flexible, or they can focus solely on one type of website. The more specialized the CMS is for the development of a specific category, the better results it should provide and better opportunities in that category, although this does not necessarily mean that, again, everything depends on the client’s requirements.

One of the reasons WordPress is so popular is that it allows for great flexibility in developing websites of all types while maintaining the same quality.

The CMS platform can be used to create the following types of websites:

  • Static web pages
  • Electronics shops (eCommerce)
  • Portfolio or blog websites
  • Discussion boards (Forums)
  • Online courses
  • Social network websites

What are the main advantages of Content Management Systems?

To comprehend all of the benefits of the CMS platform, we must first return to the previously mentioned issues that arise during website development. Most clients want their website completed as soon as possible, to be of the highest quality possible, and to be profitable. This is precisely what the CMS platform enables.

The CMS platform primarily facilitates website development for developers, speeds up the creation process, and provides a way for non-professionals who do not know how to program to create a website.

CMS, as a software platform, offers a plethora of ready-made modules that can be combined to create a website. It makes development easier and faster for developers because they don’t have to start from scratch, but instead, have a foundation from which to build. On the other hand, with the platform’s assistance, average users who do not know how to program can create a website and immediately manage it without additional training, while also having a professional-looking website.

Conclusion

In the long run, using a CMS platform for website development and management will benefit both the developer and the client. This solution has far more benefits than drawbacks, which explains its popularity.

What we didn’t mention earlier is that the CMS platform facilitates not only the website development process but also the maintenance that occurs after the website is finished and put into production. Upgrading the website is always possible and quick if it is built on a CMS platform, which is another significant advantage over other solutions.

CMS platforms are software solutions that will only improve in the future because they have found widespread applications and their future is secure.

Top 10 Developer Hobbies

Top 10 Developer Hobbies

Introduction

Developers enjoy their jobs because they are both enjoyable and challenging. There are rare situations where it can be boring. Every developer is involved in the IT world and all that it entails. Developers, like everyone else, are people. They enjoy socializing, going out, traveling, and exploring the world. It is difficult for developers to strike a work-life balance due to the nature of their work. Because programming requires dedication and focus, there is often a need to compensate for the energy expended on work.

In this post, we’ll show you how to achieve this as a developer. The solution to this problem can be found in the everyday hobbies that developers pursue outside of work hours. We will discuss the advantages of each hobby from the standpoint of a developer. If you want to improve your work-life balance and increase your productivity as a developer, you should read this post.

1. Physical activity

Developers spend a significant amount of time sitting in front of a computer, writing code. It is not a problem to sit at the computer in this manner for several days. The issue arises when this is done for an extended period of time. A pain in the lower back is one of the most common problems. Using ergonomic equipment can help to prevent or alleviate this type of problem. However, because man was not created to sit, physical activity is the best solution to such problems.

Physical activities strengthen the muscles, reducing the pain and stress that developers experience in situations like the one described above. They also aid in weight management.

Participating in physical activities outside of work is critical for developers who spend several hours per day at the computer. As a result, you may notice that a large number of developers enjoy some form of physical activity as a hobby.

Physical activities that are more popular with developers are:

  • Swimming
  • Yoga
  • Running
  • Gym
  • Dancing
  • Fitness
  • Basketball
  • Football

This hobby provides several advantages to developers. These activities not only make developers healthier, but they also reduce stress, increase focus, and develop discipline, all of which help when it comes to writing code.

2. Writing

A developer’s job appears to be simply writing code, but a good developer understands that many other skills are required to do this job successfully. Communication is one of those extra skills.

Writing is one of the hobbies that can provide numerous benefits. Writing improves communication skills and encourages the use of imagination in developers. The type of writing is unimportant when it comes to writing. Almost any type of writing provides the same benefits because it requires thought and encourages new ideas.

Writing is also an effective problem-solving tool. Writing documentation for a project can reveal a variety of new problems or provide insight into how to solve some existing ones. Furthermore, attempting to explain a complex topic orally or in writing increases the likelihood that some new idea or point of view on that topic that did not exist previously will emerge.

3. Board games

Every developer should be capable of problem solving, logical thinking, and teamwork. Board games encompass all of these elements. Developers adore social games because they incorporate everything that they use on a daily basis at work.

This hobby strengthens problem-solving abilities, communication, and creativity while also developing skills for making connections. To be a winner in a social game, one must navigate a series of complex situations and make the correct decisions. To accomplish this, the player must thoroughly analyze the game and attempt to predict what other players will do, formulate his strategy, collaborate with the team, and adhere to the game’s rules.

Board games are an excellent way to encourage some skill development through play.

4. Art

Another popular hobby among developers is art. Art is valuable to developers because it provides relaxation and inspiration. Oversaturation of information and roadblocks when solving problems are common occurrences among developers. By diverting attention away from problems, art helps to free the mind and direct it to more relaxing activities. As a result, the brain will be relieved and will have more space to make new connections and solve problems.

Today, art is a broad term with numerous definitions. Some of the commonly accepted things that are considered art are painting, music, sculptures, theater, cinema, architecture, literature, and many other things like dance, fashion, design, etc.

The benefit of art is that it is very simple to begin. It is sufficient for the developer to have the desire and imagination.

5. Cooking

Cooking is a hobby that developers have mixed feelings about. Developers either enjoy cooking or dislike it; there is no in-between. Cooking is not a hobby that provides as many benefits as the others mentioned, but it is a hobby that can be directly compared to programming.

Cooking entails combining various ingredients or following a recipe to achieve the desired outcome. Cooking, like programming, is a step-by-step process in which the steps must be completed in a specific order.

There is a constant need to experiment with and test ingredients to see what works. We must follow a number of rules when programming. The more we stick to the rules, the better our results will be. The same is true when it comes to cooking; the better we follow the recipe, the better the end result will be.

6. Reading

Reading is a unique and powerful hobby because it can be used in two ways depending on the situation in which the developer finds himself. If the developer wants to spend his spare time improving himself, he can read research-related content on a topic that interests him, from which he can learn something new or confirm what he already knows. If, on the other hand, the developer is stressed and his goal is to relax and relieve that stress, he can read content that is not related to his profession but is more fiction.

Reading is a hobby that has many advantages, the most important of which is that it encourages a different way of looking at things, i.e., a change of perspective. A developer can develop a completely different way of thinking and apply a different approach to solving certain problems by reading content related to the profession. Furthermore, this hobby helps to develop imagination, analytical, and writing skills, all of which are important in programming.

7. Video games

Gaming is a popular hobby among developers because it promotes both competition and relaxation. This hobby has the advantage of allowing the player to enter a virtual world and relax while playing with his friends. Almost every multiplayer game encourages teamwork in order to win.

Video games demand a lot of thinking and quick decision-making, demonstrating that they can be excellent learning tools. Their current popularity is not by chance. Because there are different types of games, there are a large number of video games designed for different types of players. Everyone will find something to their liking.

It is also necessary to understand how to play certain video games. However, all of these games have been designed in such a way that some basic steps can be learned quickly.

Because a large number of video games today are eSports, it is critical to play them in moderation if we want to consider video games as a hobby.

8. Music

Listening to music is one of the most popular hobbies, if not the most popular. Many developers use headphones and music to block out office noise and increase focus on their work. Unlike other hobbies, this one requires no prior knowledge except that you want to play a musical instrument.

Developers who listen to music frequently usually have playlists. A playlist is an excellent way to select music for various purposes. Listening to music during training and programming is not the same thing. You need motivational music while training. You need music that is less distracting and helps you relax and focus while programming.

Another benefit of music listening is that it can be combined with other hobbies. You can listen to music while working out, cycling, cooking, or playing video games, for example.

If you haven’t created your playlist yet, now is the time.

9. Learning

Learning new technologies gives the developer an advantage in the job market because it allows him to add another skill to his CV, demonstrating that he has more experience.

Learning new skills is essential for developers. The nature of the job necessitates continuous learning and advancement, and there is always something new to learn. Developers who view learning as a hobby have an advantage.

Because programming is demanding and exhausting, many developers prefer to pursue one of the above-mentioned relaxing hobbies. The good news is that something new can always be learned during a developer’s working day.

10. Meditation

If your primary goal is mental focus, meditation is an excellent hobby. Life today is fast-paced not only in big cities, but also in small towns. Because of the rapid development of technology, a vast amount of information is now available in everyone’s lives on a daily basis. This is significantly more than a person can handle, resulting in the problem of information oversaturation, which is exacerbated for developers due to the specialized nature of their work.

After a long day of work, meditation is an excellent way to relieve overburdened thoughts caused by stress and excess information. Programming in certain situations can cause stress, which, if accumulated, leads to frustration. Meditation as a hobby can be enough to help relax and calm negative thoughts.

This hobby improves both focus and mental health.

Conclusion

We rarely consider hobbies to be important, but they are crucial in the world of every professional. They assist us in discovering hidden passions, relieving stress, distancing ourselves from the daily routine that threatens us, and regaining lost energy. We can derive many benefits from our hobbies and achieve a perfect work-life balance if we pay just a little attention to them.
