Description

technical field

[0001] The present invention relates to a data migration method and system, in particular to a structure-oriented data migration method and system. Background technique

[0002] In the process of informatization construction, the original information system is constantly being replaced by a new system with more powerful functions. In the process of switching between the old and new systems, there is bound to be a problem of data migration. Some old systems often accumulate a large amount of precious historical data during their use from the start to the replacement of the new system, many of which are necessary for the smooth start of the new system. Data migration is the process of filtering, converting, and loading these historical data into the new system. Data migration is mainly applicable to the situation where one old system is switched to another new system, or multiple old systems are switched to the same new system, and the historical data in the ...
