Contract Management System And Implementation

With the rapid development of science technology, computer system has acted a more and more important role in enterprise management. It helps managers make decision and improve work efficiency with firsthand,accurate and comprehensive statistics which based on enterprise’s demand. Nowadays, it’s a trend that to buy or upgrade the software, which is divided into many varietis as finance management, workshop management, saves sells management, assets management, quality management, human resource management and clients relationship management,etc. on meeting with problem in enterprise management.Contract management which works closely with sales, project management and financial department is related to saves sells, finance, assets and client relationship. In traditional management, each department sets up the contract seperately on its own needs, and builds no relationships in statistics which results difficulty in contract’s supervision, track and chase. The long-term of contract receivable recover causes unnecessary losses. Contract management system records and combines the contract period and related action by a contract data sharepoint to enhance the data connections between departments and shorten the return cycle, which make the estate planning more precise and financial operation more normal.the innovation of information technology challenges the way of traditional contract management system’s implementation. With the universal use of the B/S framework, the client sides have been mostly based on web browser which highly decreases the programming difficulty and the maintenance cost, and forces C/S implemention transitioning in structure. Moreover, SSH has got increasingly favored by programmer and predominates in Java development in service sides; AJAX improves user’s experience by background data communication without refreshing the interface; JSON deals with the data redundance in the interaction between foreground and background; ExtJs, as an extensible page show control, encapsulated on Js unifies the style of interface, promotes the programming efficiency and improves the display effect. The experience accumulation in enterprise management system development makes it possible to devide business demands into slight pieces.The function module displays most direct and friendly interface like chart, list etc. by sensibly data combination, but not just data stockpiling. On the other hand, the system needs to be related with other database to enhance the interaction and realize integrated management, which puts forward higher request on expansibility and maintainability.Based on a B/S structured contract management system programmed with SSH frame, ExtJs control and applied to enterprise application, the paper is to thoroughly illuminate it by development background, core technology, function design and programming implementation in turn. Finally, I will summerize the characteristics and value in use, consider the issues in programming, and look into the future of the system.
