Police Records Management System Based On Xml Design And Implementation

File management system to provide read and write files, file access control, file sharing, and full-text search functions, but in the data or information exists on the management of data between different data models difficult to exchange and share, and search the large capacity difficulties in the storage device. Internet technology enables the sharing of data more quickly and facilitate data management experience for the public security bureau file data storage, exchange and sharing of problems, this study based on Internet technology, information exchange and sharing mechanism as proposed to XML based data management concept: the use of UML to build a data file for the standardization of the Public Security Bureau data model, users can add the required data to the XML Object in the interpretation, thus achieving a hierarchical XML Schema and relational data model of transition between heterogeneous data models, build an effective public security bureau file management system. Data objects in the design of storage systems, the application of XML and the collective of the transfer and replication function to facilitate the exchange of information, making the system structure is also conducive to large-scale, cross-platform Web-based information sharing platform.Practical application demonstrates that this subject: XML-based large-scale, cross-platform, Web-based file storage management system can achieve a lot of information in data storage access, and fine and effective queries. Also, because XML Schema hierarchical data model and relational data model the heterogeneity between the conversion, the system can easily achieve with other systems data exchange and sharing between, to meet the data management life cycle stages to perform different workflow needs.
