系统将借助数据库设计工具PowerDesigner 对数据库建模。通过对需求分析得到的结果进一步分析得到模块的具体属性以及模块与模块之间的关系模型，然后借助<br>PowerDesigner 生成逻辑模型以及物理模型，最后生成数据库 SQL 执行文件，得到对应 MySQL 数据库的表结构。

The system will model the database with the help of database design tool PowerDesigner. Through the further analysis of the results obtained from the demand analysis, the specific attributes of the module and the relationship model between modules are obtained<br>PowerDesigner generates the logical model and physical model, and finally generates the database SQL execution file to obtain the table structure of the corresponding MySQL database.
