Abstract

The embodiment of the present invention discloses a data processing method and device, which are used to efficiently establish the corresponding relationship between the data of the data source and the information of the user using the data. The method in the embodiment of the present invention includes: obtaining the use object information and SQL statement from the data source, the SQL statement includes the data stored in the data source, and the use object information is the information of the object using the data; constructing a partial query lineage according to the SQL statement, and using the partial query lineage It is used to record the processing history of the data; to obtain the data from the partial query lineage; to establish the corresponding relationship between the data and the information of the object of use. Obtain the usage object information and SQL statement from the data source, and obtain the data stored in the data source by obtaining the SQL statement of the data source. Then, construct the partial query lineage according to the SQL statement, and then obtain the data stored in the data source from the partial query lineage. In this way, the data processing device can automatically and efficiently establish the corresponding relationship between data and usage object information.

Description

technical field [0001] The invention relates to the field of data management, in particular to a data processing method and equipment. Background technique [0002] Changes in data often affect the objects of use of the data. Therefore, data migration impact analysis is required in the field of data management to analyze the objects of use that are affected by changes in the structure or location of data. [0003] The existing analysis method is to manually collect the data of the data source and the information of the user who uses the data separately. Thereby, the usage objects affected by the change of the data can be determined. [0004] This way wastes a lot of manpower and material resources, and the execution efficiency is low. Contents of the invention [0005] Embodiments of the present invention provide a data processing method and device for efficiently establishing a correspondence relationship between data of a data source and user information using the data...
