Abstract

The embodiment of the invention discloses a data migration method and device. A source system converts data to be migrated in a database into a standard data file to which the database of each structure can independently corresponds; after a first standard data file sent from the source system is received, the first standard data file is converted into database data which conforms to a second database structure; on the basis of a mapping relational table which is imported in advance, the data to be migrated in a second database is mapped to obtain target data; then, the target data is subjected to format conversion to obtain a second standard data file; and the second standard data file is sent to a target system, and the target system carries out the format conversion on the second standard data file to obtain the database data which conforms to a third database structure in the target system. Data migration difficulty is lowered, and data migration efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, to a data migration method and device. Background technique [0002] Usually, according to business needs, one system may need to use data in another system. Therefore, it is necessary to migrate the data in the database of one system to the database of another system, and the traditional data migration method can only be used for specific Data migration between systems and data migration between other systems requires the development of new data migration methods, making data migration difficult and inefficient. Contents of the invention [0003] The purpose of the present invention is to provide a data migration method and device to reduce the difficulty of data migration and improve the efficiency of data migration. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A data migration method ...
