Embodiment Construction

[0088]The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.

[0089] An embodiment of the present application proposes a data migration system that provides migration services such as full migration, incremental migration, full verification, incremental verification, migration evaluation, and structural migration. Using this data migration system, data migration can be completed between homogeneous or heterogeneous databases, and full verification is performed on the data that is fully migrated, and incremental verification is performed on incrementally migrated data. Migration assessment and structural migration can also be performed before data migration begins to analyze the feasibility of migration and improve the ef...

Abstract

The invention discloses a data migration system and a data migration method, provides the data migration system which supports universality between an isomorphic database and an isomerous database and provides a complete data migration system which can carry out full-amount migration in power-on and power-off states. A full-amount verification function carried out after full-amount migration is provided so that a user finds the problem of inconsistency in a migration process in time; incremental migration and incremental check functions in the power-on state are provided so that newly added data are synchronized in time, the real-time checking is carried out on the increment, and the problem of inconsistency of incremental data is found in time.

Description

technical field [0001] The present application belongs to the technical field of the Internet, and in particular relates to a data migration system and method. Background technique [0002] At present, a typical data migration system completes data migration through full migration or incremental migration. For example, Oracle's GoldenGate, GoldenGate is a log-based structured data replication software, which obtains incremental changes in data by parsing the online logs or archived logs of the source database, and then applies these changes to the target database, so as to realize the source database and target Database synchronization. GoldenGate can realize sub-second level real-time replication of a large amount of data between heterogeneous IT infrastructures (including almost all common operating system platforms and database platforms), so that it can be used in emergency systems, online reports, real-time data warehouse supply, transaction Tracking, data synchroniza...
