Analysis And Design Of Tobacco Monopoly Bureau Tobacco Contract Management System

The traditional tobacco production is loose management mode, main show is in scattered planting, self-management, production technical level and production efficiency is low, difficult to produce high quality products; Due to time difference and the reason of information asymmetry, farmers in a passive position, In addition, with the improvement of living standard, people to the agricultural products of external and internal indicators put forward higher request. Therefore, only development of tobacco leaf contract management system is an effective way to solve the above problem.It is based on tobacco monopoly bureau tobacco management’s actual demand, through a lot of in-depth research and analysis of the tobacco monopoly bureau tobacco role requirements contract management system; According to system requirements analysis, determine the tobacco monopoly bureau tobacco contract management system’s main function, including plant layout, contract management and system management three big functions, which is described in the form of a use case diagram of three functional modules; According to system requirements analysis, system design, including the system overall design, system detailed design and database design, system overall design gives the overall package diagram, system detailed design part function of the dynamic structure design is given, and the dynamic structure design of the sequence diagram and collaboration diagram is given. The database design, mainly including conceptual structure design and logical structure design, database design, system ER diagram and the database tables is presented. Finally, the paper summarizes and prospects, mainly summarized the own research work, and outlook for future research work.
