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. 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.
