Software is a collection of programs that enables a computer system to perform a particular task. Software is intangible. It is a logical sequence of programs and data, which can form an operating system, for example. There are different forms, executables directly linked to the computer and specific to it (for example, Microsoft is only compatible on certain PCs), or source files with their own programming language. Good software meets a specific need and performs the tasks asked of it. In addition, the software provides tasks for the computer to perform. The Berne Convention is used to protect the uniqueness of software so that it is not stolen or copied. Each creator has a license, which fixes the rights of the latter. They are also protected by trade secret laws so that software creators have a monopoly on what they have created and do not steal their data.
Web software development designs maintain, build, and transform software. Software publishers, service companies, or even freelance workers are responsible for developing the software. They can do anything. They know the software by heart. It was John Mauchly, in 1949, who developed the first programming language.
Different fields define software development, so it is complicated to define it correctly. From the systems development cycle (SDLC, which stands for “Software Development Life Cycle”), it is possible to create new software. These methodologies include software design, software development, and deployment thereof.
The original SDLC method is linear and sequential and is driven by a precise scheme:
1) identification of required software
2) analysis of software requirements
3) Detailed specifications of software requirements
4) software design
During the design, the goal is to meet the applicant’s needs and satisfy him based on specifications. For the construction of the software, the programmers write a source code and use a compiler (transformation of a source code into object code). The programmer performs tests to see if everything is going well, and there are currently no problems. In the end, all this gives the deliverable, which groups together all the files produced upstream. It can be a computer application, a component, or even a patch.
