Problems solved by technology

[0009] 1) Due to the requirement that the source and target database types must be the same, it is difficult to meet the seamless migration of data in databases under heterogeneous platforms, such as the seamless migration of data between SharePlex architecture and RealSync architecture
[0010] 2) It cannot ensure that the target database is in an active state, resulting in long downtime during data migration, such as Oracle's own component physical backup mechanism, etc.
[0011] Due to the above-mentioned technical deficiencies, it is difficult for IT personnel to solve the above-mentioned problems they face, resulting in a bottleneck that is not conducive to the continued development of technology

Abstract

The present invention discloses a system, device and method for realizing database data migration under a heterogeneous platform, wherein the system includes a source-end database, a data migration device and a target-end database connected in sequence, wherein: the source-end database changes the data of each application business Recorded in the log stream; the data migration device captures the changed data of the application business from the log stream recorded in the source database, converts the changed data together with the corresponding application business into a standard database query statement through corresponding interpretation, and Pass it to the target-side database; the target-side database completes data synchronization with the source-side database by executing standard database query statements. The invention solves the problem of database description syntax differences between different databases such as business triggering and data storage, and ensures the data consistency between the source end and the target end.

Description

technical field [0001] The invention relates to a method for data migration between different databases in computer technology, in particular to a system, device and method for realizing database data migration under a heterogeneous platform. Background technique [0002] Information Technology (IT, Information Technology) system has been in operation for a long time. On the one hand, its heterogeneity has brought greater complexity to the enterprise's information upgrade and management. The larger the data volume, the more diverse the types of business. As a result, the various operations of the enterprise are strongly dependent on the normal operation of the IT system, which makes many IT personnel face problems similar to the following: [0003] (1) How to realize the migration of customer business under different platform architectures [0004] For example, migrating customer business under a non-X86 architecture to an X86 architecture that can be continuously expanded...
