What are the Modules for Software Engineering?

Understanding modules is essential for people who wish to become software developers. In this post you’ll learn, what are the modules for software engineering.

A module is a piece of code for specific functionality in the overall software. Every module is unique and addresses the software components that can be easily solved and dealt with without disturbing the other components of the software. This is what is commonly known as the modular structure for development. Understanding modules is essential for people who wish to become software developers. People from any level of experience in programming can learn about these things in-depth with the help of various online software development courses.

Now few questions might arise, such as:

1. Why choose a modular structure for development?
2. Why not simply build an application or software without breaking it down into modules?

The reason is simple – Software contains many systems that have sub-systems, which have more sub-systems. Designing such a vast and complex system proves to be a cumbersome task as an error in one may render the entire software useless. To overcome such and other issues about software development, a full-stack software developer is needed. A software developer helps in developing software and in its maintenance and in further upgrading the software.

Modules make a programmer’s job easy, allowing them to focus on one area of the software without disrupting the flow of others. Modules are incorporated with the help of interfaces. The introduction of modularity allowed the developers to reuse pre-written codes with newer applications.

For example, Systems, Applications, and Products in Data Processing (SAP) – an enterprise resource planning (ERP) software – is comprised of several large modules (for example, finance, supply chain, and payroll, etc.), which may be implemented with little or no customization. A classic example of a module-based application is Microsoft Word, which contains modules incorporated from Microsoft Paint that help users create drawings or figures. Some more examples exhibiting the modular structure of software/applications would be YouTube, Netflix, etc., where one application has many functions.

Careers

Software developers are the software creators. They have the intellect required to create software for their client’s needs and oversee a building software team. The duties that fall under their titles are as follows:

• Developing and testing software to match the client’s and customer’s needs
• Developing upgrades for already developed applications
• Testing to check the quality and level of performance of the applications
• Documentation of work for future use

Research suggests that jobs for software developers are going to rise by 22% between 2019 and 2029. Many factors are driving the job demand for software developers regardless, it is important to note that the roles of software engineers and software developers are not the same. A software engineer is a broader field than software development.

Software developers are the “creative minds” behind the software or an application, whereas engineering is where the basic engineering principles are applied for software creation. Software developer focuses on writing code for software development, a software engineer designs and plans engineering principles for software development.

Skills

To be a successful software developer, one needs various transferrable and non-transferable skills. They are as follows:

• Problem-solving ability – One of the most critical skills a software developer should have is solving problems that users face using their applications or software.
• Teamwork – Software developers are often required to work with other developers and engineers to build prime software or applications for users. Thus, a software developer must possess a spirit of teamwork.
• Analytical and strategic – Not just software developers, but the entire field of Information Technology requires analytical skills and good strategic skills. These skills help in overcoming any hurdles that one might face in software development.

Fields

Software developers are required in almost every field, such as:

• Designing of computer systems
• Financing and insurance
• Software Publications
• Manufacturing
• Companies and enterprises’ management.

Frequently Asked Questions (F.A.Qs)

What is a module?

A module is a written piece of code associated with a particular functionality in an application or software. It may also be defined as a component of the application or software.

What is the difference between component and module?

The module is a broader term than the component. A component may refer to one particular unit of a system, whereas a module refers to a written code for a function of the application.

Are software developers and software engineers the same?

No, software engineers have a more significant role than software developers when it comes to application development. Software developers focus only on writing code for essential development, whereas engineers do the building, maintenance, and improvements in the application.

What are interfaces?

Interfaces act as a link between various modules. Interfaces define how a module will function with other modules. It tells you what kind of behavior to expect from a module, and what services it will provide without telling you “how” those services will be provided. The module’s interface describes the modules’ functions and what other modules need to do to make the modules work, without telling “how” those services will be provided.

Can we not make software without a modular structure?

Yes, the software can be made without following the typical modular structure, depending on what the software is about. The Modular design is used in software that has many functions, and hence, programming them is more accessible. However, there is no compulsion that one has to follow the modular structure.

What does a software engineer do?

Software engineer uses their computer science intellect to create, fix, and maintain software programs according to their client’s needs. They also work to implement functionalities as will be needed for the betterment of the software.

What is the work of a software engineer?

A software engineer’s work revolves around the design, test, and development of software using computer science. Some may choose to focus only on developing new software applications while the rest work to maintain and debug existing products and make them better.

What are the benefits of being enrolled in a full stack development course?

Students who have enrolled themselves for the course get access to live lectures, virtual classes from experienced industry practitioners, hands-on knowledge, and assessments that train them for real-life applications.

Is it worth it to pursue software engineering as a career?

Yes, the job demand for software engineering is estimated to rise because of the introduction of Blockchain Technology in the banking sector. The need for full stack developers is also increasing in IT, medical, government, and various other industries.
