摘要

得益于网络技术的发展，基于分布式系统的应用越来越受欢迎。在这些应用中，数据的不同副本总是存储在不同的数据库中，因此数据同步变得非常重要。本文首先对现有的数据同步技术进行了分析。然后详细描述了Oracle9i数据库中提供的Oracle流机制的体系结构和主要优点。最后，通过分析同步复制方法、异步复制方法和Oracle流方法的测试结果，验证了Oracle流的优势。

Research on Data Synchronization in Oracle Distributed System

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.
