1. Definition and planning of the problem: At this stage, software development and requirements are discussed together, mainly to determine the development objectives and feasibility of the software, and at the same time to formulate the project development plan and feasibility study report.
2. Requirement analysis: It is a very important stage to make a detailed requirement analysis of each function that the software needs to realize when the feasibility of software development is determined, which will lay a good foundation for the development of the whole software project.
3. Software design: At this stage, according to the results of requirements analysis, the whole software system is occasionally designed, such as system framework design and database design. Software design is generally divided into general design and detailed design, and the returned software design will lay a good foundation for software programming.
4. Program coding: At this stage, the result of software design is converted into computer-executable program code. In program coding, it is necessary to formulate a unified and standard writing specification to ensure the readability and maintainability of the program and improve the running efficiency of the program.
5. Software testing: After the software design is completed, strict testing should be conducted to find and correct the problems existing in the whole software design process. The whole testing stage is divided into three stages: unit testing, assembly testing and system testing.
The above is the general process of software development. Different projects and different companies may have some subtle differences, but they are generally carried out according to this process. In the development process, each stage needs the cooperation of professional technicians and teams to ensure the smooth progress of the project.
