Design And Realization Of Danda Project Contract Management System Based On J2EE Framework

Management information system is composed of people, computer and management software for information collection, transmission, storage, analysis and use of the system. With the rapid development of economic construction and scientific technology, increasingly large infrastructure project construction, enterprise needs to sign a contract type and quantity increasing, the traditional contract management level is low, however, means backward, risk prevention awareness is not strong, has been unable to meet the demand of the enterprise. So strengthening contract management informationization construction, timely and accurately reflect the dynamic information of the contract, optimizing the allocation of internal resources, perfect project contract management information system, to the company’s business decision-making, cost control, risk control has important significance.This topic in order to improve the big Dan rapid railway construction project contract management work efficiency, eliminating the risk in the project contract management, enhance the company’s industry competitiveness as the goal, based on the theory of contract management, project organization theory, the theory of project planning and project control theory and related theory, the overall demand for engineering contract management system, the functional requirements, system character and security requirements to conduct a comprehensive analysis, and the key techniques of system implementation to consider are analyzed and solutions are put forward. The system USES UML modeling language analysis system, the function of the system model is established and the dynamic modeling analysis, combined with the J2EE architecture and MVC pattern, and improve the scalability of the system. Use JSP, Servlet, JavaBean model, view and controller to realize the three roles, realize the system each function module and its key technology, establish and improve a set of project contract management system, full tracking project execution of the contract, contract management of engineering in all events in the process of execution, Dan big rapid railway engineering management for the company to provide abundant functions such as query, statistics, audit, ensure the contract data for completeness, correctness and validity.Dan big project contract management system has been put into use, through the operation of this system is used, Dan large project contract management aspects have been improved effectively, and provides a convenient staff contract information query.
