The desingn and implementation of management information system for shops stock goods ZHANG Cheng zhen (information management and information system, School of information science and technology, Gansu Agricultural University, Gansu Lanzhou, 730070) Abstract: Based on the paper analysis of small shops Invoicing business processes , it puts forward the small store management system of user needs and functional requirements, and with Visual Basic and SQL for the development tool, adopt three layer architecture development of small shops Invoicing management system. The system includes 8 function modules: user management, supplier management, types of goods, purchase management, sales management, inventory management, loss report and statistics system has good security, maintainability, reusability and easy operation. After sales, the users can accurately control the inventory in real time , speed up the turnover effectively , reduce labor intensity and improve the quality of service.
