摘要

Disclosed in the present invention are a data migration method, a data migration device and a data migration system. The method comprises: obtaining relational database table SCHEMA information from a relational database (101); mapping the SCHEMA information to a non-relational database XML model, and recording the corresponding mapping relation in a mapping relation table (102); loading the data in the relational database into the non-relational database XML model according to the mapping relation table. The technical problem of smoothly migrating the data in the relational database into the non-relational database is resolved, and the smooth conversion of service data is realized.
