Design And Implementation Of Metadata Management System For The Information System Of Quality Supervision Bureau

With the continuous advancement of information construction, the Quality Supervision Bureau and its subordinate units of the information system, the number of information systems, and the Quality Supervision Bureau of the standard "quality information resources metadata", the quality of information resources and its description, quality information resources system management, system access and database access and other information. So that the standard is suitable for the information system metadata resource sharing, publishing, data exchange, network query, etc., to promote the standardization of information system metadata.Through the establishment of a quality supervision bureau information system metadata management system which is in line with the work process of Beijing Quality Supervision Bureau, the paper constructs a comprehensive quality information system and its metadata, and improves the management efficiency and quality of public service.Because the Ministry of public security requirements for all information systems to achieve the level of protection requirements, and the record, so the system security to meet the relevant requirements, which must be achieved on the system information management, information system security analysis, from the system structure, multi functional authority, audit logs and other technical means to improve the system security, and to achieve the level of protection of the two requirements, the system of basic information, user information, user access behavior information to provide effective management functions.The metadata management system of the quality supervision bureau is based on the Windows operating system, the IIS as the middleware, and the Server SQL 2008 system database and ASP.NET, ADO.NET and other technologies are used to build this system. This system through the preliminary investigation, reasonable set up the relevant subsystems, respectively, there are three subsystems of metadata front, metadata background management and metadata extension audit. In this paper, the confrontation Supervision Bureau information system metadata management system overall function and the main technical points and related application technology were explained. And through the metadata management system for the detailed testing, the problem is solved in time. Finally, it analyzes and summarizes the achievements and shortcomings of metadata management system.
