This paper mainly discusses how to use DJANGO language to develop an online coffee mall. This system will carry out the work of each stage in strict accordance with the software development process, using B/S architecture and object-oriented programming ideas for project development.In the introduction, the author will discuss the current background of the online coffee mall and the purpose of system development. The subsequent chapters will strictly follow the software development process to analyze and design the system at each stage.
The main users of the online coffee mall are divided into administrators and members, and the realization functions include administrators: home page, personal center, member management, commodity category management, commodity information management, commodity inventory management, outbound record management, storageRecord management, sales statistics management, contact us management, message board management, system management, order management; members: home page, personal center, my collection management, order management and other functions.Because the functional module design of this website is relatively comprehensive, the information management process of the entire online coffee mall can be realized.
