Abstract

The invention particularly relates to an Oracle database synchronization system and method based on an SCN mode. The Oracle database synchronization system based on the SCN mode comprises an extraction module, a conversion module and a storage module, the extraction module is arranged in an acquisition front-end processor and is used for extracting the original data of a source Oracle database, and the conversion module and the storage module are arranged in the synchronous server. The conversion module is used for converting the received original data into a standard format, and the storage module is used for writing the standard format data into a target Oracle database. According to the Oracle database synchronization system and method based on the SCN mode, the data synchronization ofthe table structure can be realized, the automatic table building at a destination end, the total data synchronization and the real-time incremental data synchronization are supported, messages are efficiently transmitted by the aid of the CMSP distributed message service, the data transmission efficiency is greatly improved, and the method and the system have a wide application prospect in business scenarios with higher data synchronization requirements.

Description

technical field [0001] The invention relates to the technical field of database data synchronization and backup, in particular to an Oracle database synchronization system and method based on an SCN mode. Background technique [0002] With the rapid development of the information age and the rise of big data and artificial intelligence, data, as a resource, is increasingly valued by some enterprises and units, and the economic and social value of data output is becoming more and more obvious. In today's society, enterprise data is becoming more and more large and complex, showing the characteristics of huge data volume, various types of data including structured data and unstructured data, and single data storage, which will inevitably bring hidden dangers to data security and unreliability. Therefore, Data synchronization and backup are becoming more and more important. [0003] The commonly used Oracle incremental data synchronization methods are as follows: [0004] 1. ...
