Design And Implementation Of Contract Management System Based On J2EE

Contract management is a necessary part of enterprise business management. The fluent operation of contract management is good for the development of project, and is good for the development of enterprise, and is good for optimization of deploying enterprise resource. It is important for enterprise to develop information of contract management.At present contract management has some problems in Potevio company, such as can't deal with some case in time, large work of report statistics, is difficult to using contract data. To solve questions above, the paper design and implement a suite contract management system for Potevio company. The paper analyzes functions requirement, contract status, roles of system and other requirements. Based on the result of requirement analysis, some questions key to implement system proposed and some solution proposed too. The paper propose contract management flow and provide a method of contract waiting transaction remind to solve the problem of can't deal with some case in time. Toward all kinds of report table of contract management also are analyzed. Also, system safe method are provided base on analyzing the safe requirement.J2EE is kind of structure using Java 2 platform to make development, deployment and management of enterprise solution easy.J2EE core target is make unified enterprise application platform, decrease the price of enterprise development, increase the operations of platforms. The implementation of contract management using the frame of Struts and Hibernate. The System includes some layers, such as view, control, service, data access, data persistence and database.Based on above, the paper describes implementation of function module. Every module introduces some aspect as below: concrete function, static class graph and dynamic sequence graph. The paper also describe data access object and data model. Also, the implementation method is provided toward the method of safe.
