The Research On Structural Model Of Distributed Heterogeneous Database Base On XML

With the rapid development of Internet and Intranet, a large number of distributed heterogeneous databases have appeared under the network environment. Because enterprise's cooperation and application demand for government affairs electronic development, a lot of information systems need to visit the data of the distributed heterogeneous database. So need a kind of new system construction to solve information sharing of a lot of distributed heterogeneous databasesIn order to solve problem of synchronism and information sharing of distributed heterogeneous database, through developing the Information-based administrative system of water transport project and Construct and manage of Nanhua management , I have proposed a kind of structural model of system based on that the distributed heterogeneous database datum of XML technology shares. Regarding XML as effective means of information integration and sharing of the data show and data interchange standard on Web, utilizing the low-cost method ,the middleware based on XML ,to visit distributed heterogeneous database, it effectively solve the problems of data sharing and information integration .●Realizing Real-time character, synchronous, security and dependability of data processing of distributed heterogeneous database mode;●It has better settled the problem of the sharing of data;●Making synchronous processing speeds of the heterogeneous database solved.
