The design of the supermarket management system
Abstract: This paper discusses the supermarket system which is on Windows 7 as developing platform. It is on the basis of realization and management of supermarket to implement the design function and builds up the system architecture for the management of supermarket. It mainly has analyzed the pision of management of supermarket and requirements of module to discuss the processing of design and implement. It has adopted the Access 2003 and Visual Basic 6.0 as the research tool. It could adapt for the requirement of access to database, and enhanced the system’s safety and reliability greatly.
This paper mainly on the user login, user information management, supermarket information management project, delete, modify, query increase function of design and implementation are discussed. First introduced the subject of the research background, analysis of the supermarket management system status and development, and analysis of the key technologies, then the analysis and design of system. Finally describe the system implementation, and system testing.
