2. The next step is requirement analysis, which is also the stage to determine the specific ideas of normal software development. After it is determined that the software can be developed, it is necessary to analyze the software functional requirements that customers need to realize in detail. At the same time, it is necessary to consider the possible changes in the development process, formulate a demand change plan, and respond to special situations at any time to ensure the smooth progress of the software development process;
3. The next step is software design. Software design should design the framework structure, functional modules and database of the software system according to the results of the analysis of software functional requirements in the previous stage. Mainly divided into two parts: overall design and detailed design;
4. The next step is the programming implementation step. Programming is also based on software design, and all parts of software design are required to run through computer program code. Programming has unified and standardized programming rules to ensure the understandability and maintainability of software programs.
5. The next step is software testing. That is to say, after the client software is implemented by programming code according to the design requirements, that is, after the software program is completed, it is necessary to test the written program in three stages: unit, assembly and system, so as to test the correctness of the program preparation and meet the customer's needs and the adequacy of functions, so as to determine whether the software meets the development requirements, which is also a process of finding and correcting problems;
6. Complete the software development through the above core links. Next, after the software development meets the customer's requirements, the developer will hand over the software system to the customer, and deliver the software installation program, data dictionary of database, user installation manual, user guide, demand report, design report and test report to the customer, at the same time guide the customer to install the software and installation skills, and remind the customer to pay attention to the software running state, environment, detection and testing of servers and related middleware.
7. The user accepts the software development results delivered by the developer, carries out actual operation and test operation, and after satisfactory results are achieved, the user checks and accepts the developed software;
8. Customized software usually needs to provide after-sales service, regularly maintain the software, or modify the application software program according to the new needs of users, so as to continuously meet the actual needs of customers.
