Design And Research On The Key Technologies Of Publishing Business Heterogeneous Data Integration System Based On XML

The editing, printing, distribution and other information of book query is an important part of the day-to-day work in publishing, various heterogeneous application systems are independent which did not form a unified integration of heterogeneous data query platform. This thesis achieved data integration of multi-application systems in a heterogeneous environment by the multi-source data integration technology of XML. To build data sharing platform for shared database.The thesis achieved the integration of heterogeneous databases by XML by a example of book editing information system, printing information system, distribution information system and delivery information systems to achieve the goal of a unified retrieval of book management information, built a book information query platform for the integration of related staff. The thesis established a functional model, dynamic model and static model of the system based on the status and characteristics of the heterogeneous data equipment information system, by the analysis of multi-source heterogeneous data integration technology as well as based on the foundation of the XML document heterogeneous data integration and technical of exchange, completed system of heterogeneous data integration processes and design route by the application requirements for different user roles. Designed mapping and transformation model between relational databases and XML based on their Similarities and differences, achieved the integration of heterogeneous data design based on XML by designed heterogeneous data integration algorithm by XML-QL query language, and given each data source XML document data formats and detail realization of heterogeneous data integration process. Based on the design, descriped a detailed implementation of the functional module of the implementation process, the integration of application system in XML document generation and integrated database updates.The thesis construction book management information system of heterogeneous data query system functionality, performance reached the intended design goals, can meet the demand of the book information integrated information query. For many departments of the publishing to provide a unified data access interface, solves a number of system coexist in the information island problem, realizing efficient data access,to improve the level of information sharing38figures,14tables,60references.
