Thedesign And Implementationof Contract Management Information System Based On J2EE

With the increase of contractnumber and the expansion of projectscale, project contract management becomes more and more important, which directly affects the effect the projectprocess.Project contract management coversthe whole process of project management, involvingmany project participants, penetrating into the project schedule, quality and cost management, leading tothe complexity, risk, long-term of contract management.The project contract management based on traditional manual management has been unable to meet the needs of enterprise contract management, especially under the information technology development situation, establishingfull functions and clear business process of contract management information system has become the inevitable choice of strengthening project management of enterprise management.At present, some enterprises have established contract management system in a certain scale, but the current system usually emphasizes contract management information statistics management function, without closely business processcombination and contract signing process function.Aiming at meeting enterprise contract management needs, the thesis deigns contract management information system based on J2 EE. Firstly, system design related technologies and theories are analyzed including information system design, system interface technology, database and data interface technology. Then, the thesis completes the overall design from system function design, system level architecture, function module and design key system function modules such asbasic contractformation management, contract drafting, signing contract and so on. What is more, the thesis realizes core system functionsfrom process design, key core code and display interface. Finally, system core functions are tested and optimized aiming at the problems in the testing process.The thesis designsdeigns contract management information system based on J2 EE, realizing the interaction between roles and business process, pushing the sharing ofengineering information, strengthening real-time dynamic control on the implementation, providingstrong practical application and theoretical reference value.
