changing, removing, and entering important information to manage the shop such as customer and staff personal information, login, product information, and discount code It is also equipped with data to assist administrators in managing and monitoring the store's status A comprehensive mock-up, as well as a relational database, has been developed and exhibited here Bugs are also fixed by testing Lastly, a technical database was created to assist users in utilizing this system based on the mock-up B Task 1: Develop the database system 1.1 Final Mock-up of the application In the first report, I thoroughly examined the FPT shop's users and features A comprehensive blueprint of the system was created based on the existing mock-up designs from the previous assignment In order to design and enhance the system, I created a user interface in this report that combines the system's functionalities The FPT shop system interfaces are as follows: • The first is the system's login interface, which includes a login and sign-up button: Page of 86 Figure 1: Login interface Page 10 of 86
