4 System design
4.1 Main functions of system design
Through market research and consulting research, we understood the needs of users and managers, and then developed modules for administrators, salespersons, and maintenance personnel. Its functional structure diagram is shown in Figure 4-1 below:
4.2 Database design
4.2.1 Database design specifications
Data can be designed to follow the principle of separation of responsibilities, that is, system independence should be considered during design, that is, each system should not interfere with each other and not confuse data tables and system relationships.
Database naming must also follow certain standards, otherwise it will be easy to confuse. Database field names should be as similar to table names as possible. Use lowercase English letters and underscores for naming and try to use simple words.
4.2.3 Data table
This system uses the MySQL database to store data. The specific display part of the main data tables used in the system is as follows.
