The Research And Implementation Of Project Management System Based On J2EE

Now days, Beijing exploration Institute to take international general management experience in operations management, the gradual refinement of project management and control project risks, the use of means of information on the overall project plan, and audit controls. But the means of project management information, a variety of systems co-exist, including geological exploration project management system, hydrological exploration project management system, data management view is inconsistent, leading enterprises are unable to form a unified management view, therefore, to further improve the based on the need to form a unified project management system to support the management of a variety of exploration projects, improve project management complexity. We can see from the above problems, the information construction work in full swing while using a basic application platform to integrate various application systems, in order to achieve the system of information between the communication and data sharing will be the exploration of Beijing Institute of management system successfully achieved the basis of a comprehensive information technology security. Function of the system after the completion of preliminary allocation plan tasks, milestones, stage, stage node, and project risk, project tracking, real-time project status shared across the value chain, the coordination of distributed teams, managing multi-location projects.The overall system architecture relies on the Spring Hibernate JSF framework to be developed using the Eclipse development platform using the ORACLE database using the Java programming language, development project management system of Beijing exploration Research Institute under the B/S mode. UML Unified Modeling Language, to complete the system analysis and design; ORACLE and database technologies, and establish a secure database as the back-end data sources; the use of technologies such as Spring, Hibernate, build the user interface and efficient and safe connection of the end of the database access. The effective combination of hardware and software facilities, in accordance with the standards of the overall platform build. Enabling the system to achieve the desired variety of functions, improve work efficiency, reducing operating errors. Middleware-based B/S four-story structure to achieve, you can ensure that the system has a good operating performance, to achieve the design goals of the system. The developed project management system to complete portal management, project management, the planned pipeline management, plans to change the management of four major subsystems, portal management, including rights management, delegated administration, task management, document management, process management; project management sub-The system includes a new pending projects, a formal project to switch to the new formal project; planned pipeline management subsystem including the preparation of the overall schedule of the planning process decomposition, synergistic combination of the preparation of professional collaborative planning process decomposition, professional job preparation; planned change management, including creating the plan Change Request, the plan change request, the plan will be more to apply for post-processing. System construction is completed, the establishment of a unified scheme of data sources, the plan based on a unified data source layer decomposition and aggregation, in order to achieve accurate, transparent project management at all levels; realization of the project application, approval, project and other aspects of the whole management, improved The project process management, improving availability. Plan in accordance with the defined constraints to assess the change impact, and dynamic adjustments to support program coordination; plans and performs the associated. Operating plan and work completion status, system status of the school review process real-time associate, real-time monitoring of the planned state.System put into use in the process, according to the system user feedback, in line with the overall system development requirements and user needs, through the correct use of project management system to achieve the project’s accurate, transparent management, improve employee productivity and work quality while saving project management costs, creating real economic benefits.
