The Application Of Oracle Data Synchronization Technology In The Data Center Of The Guizhou Provincial Local Taxation Bureau

At present, the establishment of data centers and making user of data synchronization technology to centralize data has become the main trend of the domestic tax department, e-government, and enterprise information construction. The tax information centralized is applied widely and multi-faceted which implementation including data synchronization, processing centralized, device centralized, applications focused that are more common at home and abroad. Established the data center and had tax data centralized not only bring a series of changes to the business model, management mode and operation mode,but also propose new challenges to the sustainable development of tax information in the future.Actually, Data synchronization is the technology which is distill the data for users from the source database which is need by the target database, when the data in the source database has changed,the data in the target database will change synchronically to make sure the accuracy,completeness and timeliness of the data.This paper describes the specific application of Oracle Streams synchronization techniques in the establishment of the Guizhou Provincial Local Taxation Bureau in detail. By studying relevant principle of data synchronization technology, analyzing and contrasting the various of data synchronization technology, and analyzing Oracle data synchronization technology In-depth, and also testing Oracle Streams data synchronization technology in practical, selecting the technology which is based on Oracle Streams data synchronization to the collection and management data of the province’s tax system in the data center of Guizhou local tax. And studying combine with materialized view data synchronization technology for the further summarize, transformation and amalgamation of the data, convert, merge. It contains a complete process of Oracle Streams the synchronization project, and covers all aspects of the Oracle Streams data synchronization technology-based without losing the generality,it’s also a good reference value to the centralized project in other provinces.
