Embodiment 1

[0027] figure 1 It is a flow chart of a data migration method provided by Embodiment 1 of the present invention. This embodiment is applicable to data migration between business systems. The method can be executed by a data migration device, which can be implemented by software and / or or hardware implementation. The method specifically includes the following steps:

[0028] S110. Migrate the source stock business data in the first database corresponding to the first business system to the second database corresponding to the second business system.

[0029] In this embodiment, the business system includes an information system that provides targeted support for the business process, wherein the business process includes but is not limited to data input, business processing, file and database processing, file and report generation, query processing, etc. .

[0030] Exemplarily, the first business system may be an old business system or a business system to be migrated, and t...

Embodiment 2

[0044] figure 2 It is a flow chart of a data migration method provided in Embodiment 2 of the present invention, and the technical solution of this embodiment is further refined on the basis of the foregoing embodiments. Optionally, on the basis of the above embodiment, the method further includes: verifying the second incremental service data according to the downstream service data of the downstream service system.

[0045] Such as figure 2 As shown, the method in this embodiment may specifically include the following steps:

[0046] S210. Migrate the source stock business data in the first database corresponding to the first business system to the second database corresponding to the second business system.

[0047] S220. Verify the second incremental service data according to the downstream service data of the downstream service system. If the verification is qualified, execute S221, and if the verification fails, execute S222.

[0048] In an embodiment, when the dow...

Embodiment 3

[0057] image 3 It is a schematic diagram of a preferred example of a data migration method provided in Embodiment 3 of the present invention. Such as image 3 As shown, the method flow of this embodiment includes:

[0058] First, the source stock business data in the first database corresponding to the first business system is migrated to the second database corresponding to the second business system. Wherein, the way of migrating the source stock business data may be to synchronize the first full amount of business data in the first database corresponding to the first business system to the third database, extract the source stock business data from the third database, and Perform data processing on the source stock business data to obtain the target stock business data corresponding to the second database corresponding to the second business system, and use the load statement to write the target stock business data into the second database.

[0059] If during the proces...

Abstract

The embodiment of the invention discloses a data migration method, device, equipment and storage medium. The method includes: migrating the source stock business data in the first database corresponding to the first business system to the second database corresponding to the second business system; Send the request to the first business system and the second business system respectively; store the first incremental business data corresponding to the business request generated by the first business system in the first database, and store the first incremental business data corresponding to the business request generated by the second business system The second incremental service data corresponding to the above service request is stored in the second database. The embodiment of the present invention implements the migration of the full amount of business data to the new business system without interrupting the old business system by processing business requests in parallel.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of the Internet, and in particular, to a data migration method, device, device, and storage medium. Background technique [0002] As e-commerce enters the climax of development and the amount of data increases, there are old business systems that cannot meet the growing business needs of customers. Therefore, people will upgrade the old business systems, but what follows is how to upgrade the old business systems Migrate a large amount of data in the upgraded system. [0003] In the existing technology, the commonly used data migration method is to migrate the existing business data first, suspend the online business after completion, ensure that no new business data will enter the old system, and then migrate the incremental business data, and then start the new system. [0004] Based on the above-mentioned existing technical solutions, when data migration is performed, in order t...
