Problems solved by technology

The problem with the general incremental synchronization method is that the logic of data generation and processing by the producer and the receiver is not simple, and it is easy to cause data inconsistency after a long time; the disadvantage of full synchronization is that as the amount of data increases, the full amount of data is very large. It is very difficult to process and synchronize data; and data is easily lost in both ways. If some or all of the data is lost for some reason, the consequences will be unimaginable

Embodiment Construction

[0017] In order to make the measures, creative features, goals and effects achieved by the technology of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0018] figure 1 It is a flowchart of an incremental data synchronization method in the present invention. First, obtain the data manipulation language 101 of the source database; then, export the data manipulation language as a data package 102; synchronize the data package to the target database 103; set a time period in the time module, and update the data 104 of the target database; further , parse the data packet into query language and change data 105; and synchronize the query language and change data to the target database 106; finally, in the target database, generate and store the form 107 that needs to change the data and the form 107 after the change data.

[0019] The functions used in the present invention will be furthe...

Abstract

The invention belongs to the technical field of databases and provides an incremental data synchronization method. The incremental data synchronization method is characterized by comprising the steps that firstly, the data manipulation language of a source database is obtained; secondly, the data manipulation language is derived and serves as a data package; thirdly, the data package is synchronized to a target database; fourthly, a time quantum is set through a time module, and data of the target database is updated; fifthly, the data package is analyzed into the query language and change data; sixthly, the query language and the change data are synchronized to the target database; finally, in the target database, tables needing data changes and tables on which the data changes are conduced are generated and stored. The incremental data synchronization method effectively resolves the problems that logic repetition exists, the data are not consistent, the data are difficult to process and synchronize, and the data are obliterated easily.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to an incremental data synchronization method. Background technique [0002] There are two methods of data synchronization, one is incremental synchronization, and the other is full synchronization. The problem with the general incremental synchronization method is that the logic of data generation and processing by the producer and the receiver is not simple, and it is easy to cause data inconsistency after a long time; the disadvantage of full synchronization is that as the amount of data increases, the full amount of data is very large. It is very difficult to process and synchronize data; and data is easily lost in both ways. If some or all of the data is lost for some reason, the consequences will be unimaginable. [0003] Therefore, there is an urgent need in the field of database technology for an incremental data synchronization method that is simple in logic, consistent ...
