Design and Implementation of Data Management Center Based on Web Services

摘要

In a large e-government system, different government departments have already created and are going to create a large number of heterogeneous databases. Only using data replication and synchronization technology as the low level infrastructure to maintain the huge system is very difficult to get satisfactory result. A data center constructed with Web Service technique and XML schema can give a good solution to problems with business logic method invocation and transparent data exchange in low layer, and thus achieve better data sharing and integration.
