1.4 Research content and methods
1.4.1 Research content
The design of this online ordering system mainly includes two parts: user function module and administrator function module. Among them, the main function modules of the user part include registration and login, information management, order management, and evaluation management. The functions of the administrator part mainly include system management, order management and dish management.
(1) User function module: including functions such as adding table numbers, modifying table numbers, adding notes, adding dishes, deleting dishes, querying dishes, paying for member discounts, and paying for ordinary users; user information management functions include viewing historical orders, viewing personal Information and modification of personal information and other functions; login management functions include functions such as registering an account, logging in to an account, and logging out of an account; evaluation management functions include functions such as adding comments, deleting comments, and adding additional comments.
(2) Administrator part: including modules such as dish management, system management and order management. In the dish management module, the administrator can replace the dish carousel, add new dishes, delete expired dishes, and modify the unit price of dishes, dish material descriptions, dish inventory and other related information; in the system management module, the administrator can Perform information review and user management for newly registered users, and at the same time modify the administrator's login password and other functions; in the order management module, the administrator reviews the order submitted by the user, and at the same time can view the user's order details and user evaluation details.
