In this paper, at first, introduces the selected topic background, significance of this topic, and talks about the research status at home and abroad, next the paper introduces the research content and main work I have done in my paper. Then introduces the technology which uesd in the system. Next, analyses the system demand, including business requirements, functional requirements, data demand, non-functional requirements. At last, describes various modules and the chart, including the system overall design, system detailed design, database design.In business requirements analysis, according to the needs of the business, describes the systems business by business process diagrams.

In system design in detail, using the package diagram, class diagram, sequence diagram, core activity diagrams, detailed introduces the system design of content. In system database design, describes the system database entities and relationships between the entities by ER chart, introduces the table structure in the system in detail.At the end of the paper, summarizes the paper and the future prospects.
