Design And Implementation Of Technology Project Management System Based On J2EE And Workflow

In recent years, with the rapid development of State Grid Corporation of China, capital expenditure of the company in the amount of remained at a high level, many types of projects, increased project financial management workload, differ in some important project financial management, in order to avoid financial risk, and further enhance the level of financial management project, to promote the construction of financial management all engineering, standardization, decision based on the "project financial management standard" implementation process management system of IT project finance.The project financial management and related research system has been extensively studied including development background, domestic and foreign research, and combined with the advanced information system development tools and key technologies. Research results to seamless collaborative ERP and office system two both independent and can be carried out according to the level of data exchange, improve operational efficiency, realize the exchange may week maintenance plan management, using the workflow implementation project, contract and project management Gantt chart to analyze Internet user experience design experience of personal work, financial management to achieve integrated and seamless engineering. Through the analysis to determine the performance of the HTML5+CSS+Javascript layer, business layer and the logic layer using the J2 EE services architecture, finally data layer using Oracle database management, design a system based on four layer architecture of B/S structure, in order to realize the workflow based, graphical platform for display, to flow closed loop maintenance as the link, graphics project financial management based on workflow.The whole project life cycle according to the software development project management requirements in practice, complete the system feasibility analysis and demand analysis and detailed enough, using V development model; must be in the outline design and detailed design stage output unit test cases and integration test case, milepost guarantee of each stage can effectively control; after the realization of the system, are the performance testing, the indicators of concurrency, reliability reaches the design.
