In view of the SMEs development and the purchase-sell-stock management system is one of the important topics that puzzle many software developers.This paper is based on the actual project of Daqing Hongda Macro electric appliance; describes the necessity of the purchase-sell-stock management system in the SMEs, combined the actual situation and the special needs of enterprise, create development system structure based on C/S mode, guarantee the system of data security, and speed up the operation of the system speed. The paper also elaborated the whole process of analyses, design, and practice of Macro electric appliance according to the software development ideas of software engineering. The paper give out system analysis stage and the cause of the data flow chart and use case diagram, the function of the system design stage structure, UML dynamic modeling sequence diagram and the activity diagram and database design phase of the various table structure, and, the measuring method of putting into operation system before the white box and black box combined.Hongda Macro electric appliance purchase-sell-stock management system contains nine modules, such as basic information management, purchase information management, sales information management, money can be pumped management, inventory information management, information management, statistical analysis management, function management, and system help management.
