This stage is mainly used to determine the goal, effect and feasibility of software development.
Demand analysis stage
After determining the feasibility of software development and defining the development goal, it is very important to analyze the functional requirements of the software in detail. Although the current agile development method and Shandong software development process are constantly adjusted with the changes of users' needs, the initial requirements analysis is still very important and is the basis of the whole software project. Moreover, a complete and reasonable demand analysis can cope with the changes in the development process and ensure the normal operation of the whole project.
Software design stage
Software design is to design the whole software system according to the results of demand analysis. Including system framework design, database design, etc. , divided into overall design and detailed design. Software design also lays a good foundation for software programming.
Program coding stage
Program coding is to convert the design results of software into computer-executable programs. Attention should be paid to the coding specification in program coding to ensure the readability and maintainability of the program. And pay attention to improve the running efficiency of the program.
Software testing stage
After the software is written, it must undergo rigorous testing. Software testing is to find problems that have not been found in the program, find bugs and correct them in time. Testing can be divided into three stages: unit testing, assembly testing and system testing. There are two testing methods: white box testing and black box testing.
