Abstract
The purpose of the group purchase system design is to provide users with a platform
for product classification, product information, orders, and other aspects.
Compared to PC applications, the design of a group purchase system is mainly aimed
at businesses, and aims to provide a group purchase system for administrators, users, and
businesses. Users can view product information in a timely manner through the APP.
The group purchase system is an application platform under the Android operating
system. To prevent compatibility and stability issues, Express is selected as the framework,
and the data storage between Android APP and backend servers is mainly through
MySQL. The data generated by users when using the application is passed to the database
through languages such as Node.js. In this way, it promotes the efficiency of information
flow and data transmission in the group purchase system, providing a group purchase
system that is rich in content, diverse in functions, and easy to operate.
Key words: group purchasing system; Node.js language; MySQL database
