2. Overall Design:By analyzing the requirement information, the system's external conditions and internal business requirements are abstracted and modeled to form a summary Design Description document.
3. Detailed Design:This part carries out a detailed system design (including some code instructions) on the basis of the requirement and outline design ).
4. Development and programming:Code the system.
5. Test Analysis and system integration:Perform simulated data testing and other correlation tests on all functional modules and integrate the functions of all modules.
6. On-site support:The system goes online for trial run to record and answer on-site questions.
7. System Operation Support:After the system is officially launched, necessary maintenance and BUG changes are made to the system.
