现如今已是2020年，人们早已处于大数据时代中，计算机更是成为人们日常

It is now 2020, people are already in the era of big data, and computers have become an indispensable tool in people's daily lives. The company's business management model has already transitioned from manual office management to computer information automation management. Owners of some small shops may use computer management for sales and bookkeeping for the convenience of sales. Almost all large companies use computer information processing systems to automatically operate and run equipment or machines. For some small and medium-sized supermarket products , Sales, employees and other information management, can also be connected to the computer for management, the management manager through the computer clearly controls the work of the entire supermarket. For this, I used Visual Studio 2017 launched by Microsoft Corporation for system development and design. The database operation software is Microsoft SQL server 2008, which stores various information inside the supermarket. This database makes the internal information of the supermarket have high integrity, consistency and security, and is connected to the database through ASP.NET. In addition, the design also uses StarUML drawing software to draw the class diagram and use case diagram of the system information. The system can manage the information in the supermarket, such as six functional modules such as purchase, sale, and return. It also includes administrator login, registration and other functional modules, mainly adding, deleting, modifying, and inquiring operations. Problems such as complicated data and difficult management provide more flexible and convenient management methods for various supermarkets.
