Actual combat of MySQL database design project of online mall system

explain ： This is a practical project of database course design （ Incidental Code + file + Video Explanation ）, If you need Code + file + Video Explanation You can get it directly at the end of the article .

 

Project background

        The development of the Internet has allowed various industries to break through the traditional development fields , Industrial functions continue to evolve , Achieve multi domain symbiosis of the same content , Unprecedented expansion of the traditional industrial chain , At present, the whole cultural and creative industry has set off a wave of cross-border integration , Constantly release new productivity , Stimulate industrial vitality . This project is based on a Online mall system As an example to introduce the database design in Internet industry development Application skills in .

System function description

        This project introduces a be based on MySQL Database online mall system . The functions of the system mainly include user login and authentication 、 Commodity management 、 Delete item 、 Order management 、 Modify order status and other functions .

        The whole project starts with the login interface , After the user enters the user name and password , The system verifies whether the user exists by querying the database . If the verification is successful, enter the system main menu , Users can choose to operate the corresponding functions in the online mall .

System function analysis

A simple online mall system includes user login and authentication 、 Commodity management 、 Delete item 、 Add the goods 、 Order management 、 Modify order status and other functions , This section will learn about these functions and implementation methods .

The functional structure of the whole system As shown in the figure ：

  The data flow of the whole system As shown in the figure :
