Design And Implement Of Sichuan Province Sport Lottery Management Center Office System Based On Ajax

The source of this dissertation is the project called Sichuan province sport lottery management center office system, abbreviate LMIS system. This system is developed with Arena dsigned by company- Beijing Bestinfo and its structure is B/S. According to LMIS system's and Arena's requirement and traditional B/S system's deficiency, the system uses Ajax technology to build an effective and good interactive B/S system.This dissertation introduces the background of this project, the total design of LMIS, the detail design and the implementation of functions in LMIS. In the total design of LMIS, it describes the entity relational graph which is to explain the relation of tables in database. In the detail design and the implementation of functions about LMIS system, it introduces the structure of functions about information-release, sale-station renaming and prize-analyzing. There are three sub-functions in the module of information-release. They are sending-information, releasing-information and querying-information. There are four sub-functions in the module of sale-station renaming. They are inputting-application, examining and approving-application, transacting procedures and renaming. There are three sub-functions in the module of prize-analyzing. They are drawing-information, distributing-prize and detailed information of querying.It explains the design of all sub-functions about these three function models through data flow diagram and IPO (input/ process/output) diagram and the implementation of them in detail. Then it gives the testing results of information-release module and the analysis of these results. According to the results, the designers make the information-release module better.LMIS system is strictly designed and implemented in accordance with the idea of software engineering. According to requirement analysis of LMIS system, designers finish preliminary deisgn, detailed design and coding. Then, doing testing with testing caeses is the last step to achieve the total system. LMIS is a platform for sharing information.
