Embodiment 1

[0023] Such as figure 1 As shown, the embodiment of the present application provides a data migration method, wherein the method includes:

[0024] Step S100: Obtain data information of the source system;

[0025] Specifically, data migration is the process of selecting, preparing, extracting, transforming, and permanently transferring data from one computer storage system to another. In addition, verifying the integrity of migrated data and decommissioning old data stores are also considered part of the overall data migration process. The source system is the original system that needs data migration, and the original data information in the database of the source system is obtained, including transaction data information, cash flow data information, accounting data information and other original data information.

[0026] Step S200: Obtain the target system;

[0027] Specifically, the target system is a storage system for data migration and transmission, and data analysis...

Embodiment 2

[0092] Based on the same inventive concept as the data migration method in the foregoing embodiments, the present invention also provides a data migration system, such as figure 2 As shown, the system includes:

[0093] A first obtaining unit 11, the first obtaining unit 11 is configured to obtain data information of the source system;

[0094] A second obtaining unit 12, the second obtaining unit 12 is used to obtain a target system;

[0095] A first analysis unit 13, configured to analyze the target system and divide the data information into first static data and first dynamic data;

[0096] A third obtaining unit 14, the third obtaining unit 14 is configured to map the first static data to the target system, and obtain second static data, wherein the second static data is migrated to the target system the first static data;

[0097] A fourth obtaining unit 15, configured to split the processing logic of the target system to obtain multiple sub-processing logics;

Abstract

The invention discloses a data migration method and system, and the method comprises the steps: obtaining data information of a source system; obtaining a target system; analyzing the target system, and dividing the data information into first static data and first dynamic data; mapping the first static data to the target system to obtain second static data; splitting the processing logic of the target system to obtain a plurality of sub-processing logics; according to the first dynamic data, enabling the static data mapped to the target system to be subjected to batch processing through the multiple sub-processing logics, obtaining second dynamic data, wherein the second dynamic data are the same data as the first dynamic data in the target system. The technical problem that in the prior art, the difference between a new system and an old system is large, if a traditional library table mapping mode is adopted for data migration, large uncertainty exists, and consequently data cannot be directly mapped to a new system is solved.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a data migration method and system. Background technique [0002] At present, data migration is mainly through database table mapping, analyzing the mapping rules at the field level, and implementing migration by writing stored procedures. In some complex scenarios, some code blocks may be used to assist in the implementation. The data migration method of the original library table mapping is increasingly unable to meet the current needs, which is mainly reflected in the replacement of the old and new systems, including the differences in business logic, modeling methods, and business drivers between the old and new systems. Often the new system has stronger and more flexible functions, and the heterogeneous design between systems becomes more and more obvious. The more new functions of the target system, the more powerful the problem will be. Old data cannot be discarded. New...
