Plm Component Library In The J2ee Platform, The Design And Realization

With the complexity of software systems to increase, growing large-scale software. People gradually realized that in order to really bring about the industrialization of software production, the development of the software industry to the needs of software productivity and quality, use software reuse is a realistic and feasible way. Software reuse as an important way, and component-based software reuse received widespread attention and application. With the in-depth development of the area, it has been accumulating a large number of components being used in the field in software development organization, people strongly hope that as much as possible to reuse existing software components built the new system in the field. It is meaningful that research on how to store the existing reusable components, provide a good base to the staff of application systems in the area,and make components be used and managed in the field of rehabilitation effectivly. Component library as a support software reuse infrastructure have been industry and academia more and more attention, it can provide the component description, classification, storage and retrieval capabilities.This paper first detailed software reuse from the historical background, the definition of software reuse, and classification ,then in conjunction with PLM projects, the main component is based on the PLM system analysis and design, respectively, from the system needs analysis, development environmental structures, systems architecture and the development of components to detail. The needed component in the development of PLMsystem and the new component should be stored and managed by component library. The paper gives a framwork about a PLM component library system after learning those exsiting component library systems,and describes the funcation of PLMCLMS by uml-case.Then introduce a classified construction that the components are classfiied to nine level based on the Hierarchical classifcation schemes,and the method of facted semantic describe and interface syntax describe. In the end, it writes up the method of how to retrieve compoment by the facted tree and match componet by the interface definitation. It is heplf to develop the PLM system quickly and raise the efficiency of component reuse.
