Abstract

The embodiment of the invention discloses a data processing method and device, which are used for efficiently establishing a correspondence relationship between data of a data source and the information of a usage object using the data. The method of the embodiment of the invention comprises the following steps: obtaining use object information and SQL statements from a data source, wherein the SQL statements include data stored in the data source and the information of the usage object is information of an object using the data; according to the SQL statement, constructing the local query lineage, and using the local query lineage to record the processing history of the data; obtaining the data from the local query lineage; establishing a correspondence relationship between the data and the information of the usage object. The information of the usage object and SQL statements are obtained from the data source, and the data stored in the data source are obtained by obtaining the SQL statements of the data source. Then, the local query lineage is constructed according to the SQL statement, and the data stored in the data source is obtained from the local query lineage. Thus, the data processing device can automatically and efficiently establish a correspondence relationship between the data and the information of the usage object.

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...
