Web Services-Based Design of Heterogeneous Database Retrieval System
Abstract
In the work of office automation and information construction, there exists a most important question in the system of computer information intergration: how to fully use several of existing database resources to realize the connection, database exchange and sharing among different databases; and how to make them work together harmoniously. In order to improve the database exchange among different databases and to solve the cooperation task among them, this set of heterogeneous database the data retrieval system is developed.
The main function of this system is to realize the data conversion of different databases, the elimination isomerism and the retrieve of assigned data of the different database. The system reaches its function by using C/S model of system, computer language development of C#, XML as well as connection technology of Oledb; WebServices. This kind of WebService heterogeneous database data retrieval system has provided a new-brand solution for the digitized resources conformity use. In addition, the present situation of database needs the adoption of isomerism database union urgently and it will be long-standing.
