Software Development Fundamentals

Preface

T echnology and its advancement have paved a way for the success of many different business companies and organizations. Many studies have been conducted, and it has been found that the businesses' that have a good online presence, have good online marketing strategies tend to have a better chance of revenue generation than those who lack the same.

Software development is defined as the process of writing and maintaining the source code and also includes the processes which are involved in the formulation of the desired software and the final display of the software in a planned or structured manner. A team of people holding expertise in them on the field of work is gathered to develop and manufacture the product.

Software development is a complex process and consists of several steps to reach the final step. Also, there are different models present on the software development life cycle functions. Each of these models works on a different principle, and the optimal model is chosen by the developer on the basis of how they want their product to be. It is not possible to develop software in a single go. It is tested again and again and is put out to use by the potential customers and their valuable feedback is taken. This feedbacks are then incorporated in the product along with adding appropriate features if required, and then are again presented to the customers and the same cycle continues until the customer finally likes and approves the product.

It is a known fact that the emergence of technology has been a boon to almost every industry. It has been found that the user spends most of their time on the phone while surfing through different apps. For a business company or organization, the customers are the most important thing in the world. If a business company does not have loyal customers, then the business entity holds no value. Software development acts as the medium of bridging the gap between the customers and the business enterprise.

Summary

S oftware development is defined as the process of inter-related computer science activities that work towards the process of designing, creating, employing, and supporting software. The development of software is carried out by professional software developers, software engineers, and programmers or coders. Other professionals, like hardware makers, device fabricators, and scientists also work collectively and help in the process of software development. As the word itself suggests, the basis of developing software is the software itself. Software is defined as the set of programs and instructions which commands the computer about what to do and what not to do. There are four types of software- programming software, application software, system software, and embedded software.

Software Development Life Cycle tells us about the different stages involved in the development of the software, starting from the conception of the idea of software development until the final stage of the retirement of the product. SDLC plays an important role in making and building the product in a pre-defined disciplined and systematic manner. The main aim and the purpose of the SDLC are to deliver a high-end product following the requirements of the customer. The SDLC is comprised of the seven steps- Planning, Feasibility Analysis, Product Design, Coding, Implementation & Integration, Software Testing & Installation, and Maintenance.

It is important to follow a specific life cycle to complete the project successfully as it makes the process of management easier. Every SDLC model has its own set of advantages and disadvantages. The model that best fits the project is determined by many factors like Requirements, project size, the complexity of the project, limitations of skill, and cost of developing the project. The life cycle model is referred to as the descriptive representation of the product development cycle right from the start that is the inception of the product till the end of the product that is when it has been released in the market or to the potential client or customer. The waterfall model is the basic model and the rest of the other models are based on this model.

It has now become important for the business companies and the organization and for the entrepreneurs as well to be well-versed with the art of software development process especially if the company is a software enterprise or a mobile app development company. To be a successful businessman/businesswoman, they need to take the business over to the online marketing platform as well. The business operators need to move over to online measures and mobile apps as they greatly affect how the customers get to know about your product and services and use them. Big revenues can be generated easily in a smaller amount of time if one knows the art of online marketing and software development.

Chapter 1: What is Software Development?

S oftware Development can be defined as the process of designing, programming, specifying, documenting, testing, conceiving, and bug fixing, which together help in the process of developing and maintenance of different frameworks, applications, and the other components of the software.

According to the IBM Research, Software development is defined as the process of inter-related computer science activities that work towards the process of designing, creating, employing, and supporting software.

It is also regarded as the process of writing and maintaining the source code and also includes the processes which are involved in the formulation of the desired software and the final display of the software in a planned or structured manner. Therefore, Software Development can be referred to as the process which includes various activities like modification, prototyping, reuse, maintenance, re-engineering, research, new development, and other such activities that are involved in the development of software and software products.

Development of software serves a variety of purposes such as it can be used to fulfill the certain needs of specific client or business, it can be used to meet the apprehended needs of the potential users or lastly can be used for complying with the needs, demands and its use by self.
