Problems solved by technology
[0004] First of all, since the executed data operation statements are captured at the application layer, there are quite a lot of restrictions when synchronizing the data of a certain table or some tables alone. For example, it is necessary to know which data operation statements correspond to the tables that need to be synchronized;
[0005] Secondly, the tables related to these data operation statements must be synchronized together, the efficiency and speed of synchronization are relatively low, and the operation of synchronizing to the target database may fail

The invention provides a data sheet synchronizing system and method. A source data sheet and a data sheet task are locked through a data synchronization extraction program, the current task of the current data sheet is only executed, variable data and incremental data, namely data change and differential section of the source data sheet of the current time and the source data sheet during last extraction, different from variable data and incremental data during last extraction in a source data sheet to be synchronized can be rapidly extracted, and thus speed and efficiency of synchronizing the data sheets among databases are improved; and after a target data sheet is locked by a data synchronization merging program, compared with the source data sheet, the data sheet synchronizing system and method disclosed by the invention are used for confirming the incremental data again and ensure data sheet synchronization safety and reliability. Furthermore, a local area network is connected with Internet, data synchronization under a low network speed environment can be supported, and one-to-many data synchronization expansion can be completed.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a data table synchronization system and method. Background technique [0002] At present, the basic principle of the most common software implementation method for fast synchronization of data tables across networks and databases is to capture the data operation statements executed on the source data tables at the application layer, and package and transmit the captured data operation statements to the target database. end, execute data operation statements on the target database after decompression. [0003] This method has the following disadvantages: [0004] First of all, since the executed data operation statements are captured at the application layer, there are quite a lot of limitations when synchronizing the data of a certain table or some tables alone. For example, it is necessary to know which data operation statements correspond to the tables that need to be s...
