Embodiment Construction
[0031] See figure 1 As shown, the present invention obtains and analyzes the operation performed by the database in real time by monitoring the log of the source data, performs data encapsulation on the performed operation according to the protocol, and pushes the data to the target server; after the target server receives the data, it The data is verified. If an error occurs, the data is requested again for this time. Otherwise, the data is added to the data queue and waits for the data to be written into the database.
[0032] The system is mainly composed of a monitor, an analysis query device, a data organizer, a data checker, a data queue and a reader-writer. The monitor, analysis queryer and data organizer are at the data source; the data checker, data queue and reader are at the data synchronization target. The monitor monitors the log of the database, and when the log file is updated, it sends a message to the analysis queryer to remind; the analysis queryer finds the...
