The Design And Implementation Of Production And Maintenance Management System Based On J2EE

Production and Maintenance Management System (PMMS) is an information system to support the daily operations of Beijing Subway Signal Company. Its main functions include the operation failure statistics, analysis, export of communication signals in the process of metro, the maintenance plan, implementation, tracking of the communication signal equipment of each line, and the supplies in the process of management. PMMS project makes Signal Company’s traditional complex fault management and production planning become centralized management style, flexible, paperless and enhances the level of enterprise information.This paper analyzed PMMS of the project background and enterprise system development related technology of J2EE was introduced in detail. Around the Dorado, Spring, Hibernate framework technology, it introduced PMMS project characteristic of the technology of J2EE framework used to, and made the overall PMMS project system function modules to be divided. Use cases of each function module were introduced in detail.PMMS project’s examination and approval of the business process is step by step, with permissions fine granularity requirement and system data interaction high performance requirement needed. Based on the above characteristics, a single software framework can not meet the diversified demands. Project development frameworks for the integration of a number of excellent play their own technological superiority. Based on PMMS project as the background, first the paper introduced the system of five layer architecture models, described the design of the function modules and database of the system. Second the paper introduced the concrete application system frame in every hierarchical structure, and expounded the advantage of framework’s technology integration brought to the software system. Third the paper described the design and implementation of the main business function modules of PMMS under the DSH framework integration environment and the integration configuration of the permission management module and the function modules with the display pages. Finally the paper summarized the application of DSH framework for project development and the system performance for the convenience brought by the enhance layer.
