Abstract


This thesis is based on small and medium manufacturing enterprises to product data management requirements in a broad reference to an existing commercial PDM system and conduct a thorough investigation to SMEs based on the research to microcomputers and Windows Server operating system for the application platform to Microsoft SQL Server 2000 for the database system to Microsoft Visual C 6.0 for the development of tools to develop a based on client / server architecture for manufacturing information integration and support concurrent engineering product data management (PDM) system permissions management module. The article first describes the basic concepts of product data management, product data management through the historical background, brief history of the development of domestic and foreign-based analyzes and summarizes the research status of this topic. This paper introduces the PDM system architecture and main features, and special automobile manufacturer based in Hanyang field research situation analysis summarizes the characteristics of small and medium enterprises, SMEs demonstrated PDM system in the enterprise market demand, and accordingly proposed This thesis aims and main research content. The paper also details the approval workflow systems, workflow systems, and based on the user - organization - the roles of three common PDM access control management model, the traditional model of analysis and research, summarize the previous model defects propose suitable for small business access control management model should satisfy the characteristics. The article also details the current theories of PDM systems and support techniques, including architecture, PDM, PDM system construction method, object-oriented way of thinking, database technologies, object modeling technology and client / server technology. In view of object-oriented software implementation throughout the PDM system to start in a pivotal role, the article particularly object-oriented way of thinking from the basic concept, made a progressive approach to the discussion, and on this basis proposed PDM system architecture and establish a model to achieve access control management structure. Thesis focuses on access control management section to do a more detailed analysis, and on this basis proposed access control administration model. Posts in the last chapter introduces centralized analysis and management model to achieve this access control database design, based on the idea of ??the model, the model involved in the relevant functional parts made eleven interface design analysis software to achieve the ultimate success systems.
