Software development process

1. Requirements analysis: through the understanding of customer business and discussion with customers on the process of the basic modeling of the requirements, the final formation of the requirements specification.

two。 Overall design: through the analysis of requirements information, the external conditions and internal business requirements of the system are modeled abstractly, and finally a summary design description document is formed.

3. Detailed design: this part carries on the detailed design of the system (also includes part of the code description) on the basis of the requirements and outline design.

4. Development programming: code the system.

5. Test analysis and system integration: carry out simulation data testing and other correlation tests on all functional modules and integrate all module functions.

6. On-site support: on-line trial operation of the system to record and answer on-site questions.

7. System operation support: after the system is officially put into production, make necessary maintenance and BUG modification to the system.
