Benefiting from the development of network technology, applications based on distributed system become more and more popular. In these applications, different copies of data are always stored in different databases, so the data synchronization becomes very important. Firstly, this paper analyzes existing data synchronization technology. And then it describes the architecture and the major advantages of the Oracle streams mechanism that is provided in the Oracle9i database in detail. At last, it verifies the advantages of the Oracle steams by analyzing the test results of synchronous replication method, asynchronous replication method and Oracle streams method.
