Software development is generally divided into five phases

Software development is generally divided into five phases:
1. Problem definition and planning
This stage is a joint discussion of software development and requirements, mainly determining the software development objectives and feasibility.
2. Demand Analysis
When determining the feasibility of software development, perform detailed requirement analysis on each function that the software needs to implement. The demand analysis stage is a very important stage. This stage will lay a good foundation for the development of the entire software project. "The only thing that remains unchanged is the change itself." The same software requirements are constantly changing and going deep in the Process of loving you. Therefore, we must customize a demand change plan to cope with such changes, to protect the normal operation of the entire project.
3. Software Design
In this phase, the entire software system should be designed based on the results of the requirement analysis, such as the system framework design and database design. Software design is generally divided into the overall design and detailed design. Further software design will lay a good foundation for software programming.
4. program code
At this stage, the results of the software design are converted into code that can run on the computer. In program coding, unified and standard compiling specifications must be formulated. To ensure the readability and maintainability of the program. Improve program running efficiency.
5. Software Testing
After the software design is complete, strict tests should be carried out. Once problems in the software design process are found and corrected. The entire test phase is divided into three stages: unit test, assembly test, and system test. The testing methods mainly include white box testing and black box testing.
