Abstract

The present application provides a data migration method and device. The method includes: the data migration device determines the target data required to carry out the target business; the data migration device migrates the target data from the original database to the new database; the data migration device transfers the target data in the original database except the target data Other data is migrated into the new database. This application can improve the flexibility of data migration, and is conducive to timely and rapid business development.

Description

【Technical field】 [0001] The present application relates to the technical field of databases, in particular to a data migration method and device. 【Background technique】 [0002] A database is a collection of data that is stored together in a certain way, can be shared by multiple users, has as little redundancy as possible, and is independent of the application. During the use of the database, when the storage structure of the database cannot meet the business needs, the data in the database needs to be migrated to a new database that can meet the business needs, which involves the problem of migrating a large amount of data. [0003] At present, data migration generally migrates data from the original database to the new database sequentially from the earliest data according to the storage time of the data. This data migration method has poor flexibility and cannot conduct business in a timely and rapid manner. 【Content of invention】 [0004] Various aspects of the pre...
