| Along with the progress of the society, the development of IT industry becomes faster and faster. The problem becomes more and more. In situations of many data types and the chaos of data conducting to difficultly manage, product data management appeared. Meanwhile, because in the management process, the emergence of security issues, based on the role of access control was born. But still needs to solve the technical problems, it will be what the information industry must research. And also what the system design should solve.The thesis came from the temporary project of elevator design company, according to the actual needs of the elevator design system, used the three layer structure mode (MVVM)、C#and Silverlight technology developed elevator data management system based on the WCF RIA Service. This system in the way of management is different with the previous Product Data Management (PDM) in using the latest technology and combined with the actual demand of the elevator company, rising more convenient, more functional and complete. The most important of system is to realize the user Role Based Access Control (RBAC) Management called System User Management and Product Design Management. Administrator permissions can be set up to strengthen the security of the system, but also completed the concentration of dynamic and flexible management to the related elevator data.In this thesis, firstly the background related to the topic and research situation domestic and abroad is introduced,then the technology related to system development and theories are explained in detail, the system needs are analyzed and illustrated later. the whole system architecture design,function module design,database design and system safe design are given, at the same time, the detailed design process is introduced. At last, the thesis completed the process of the system implementation and testing, summarized the system, proposed the shortages and the places needing to improve. |
