Abstract

The invention discloses a data extraction method and device. The method includes: analyzing the acquired data extraction task of the source system, and generating a data extraction list corresponding to the data extraction task according to the data partition granularity; Extract the data capacity in the list, and determine the data extraction method for the source system; if the first preset data extraction method is used for data extraction, extract the data of each of the data partitions, and generate the first data file , saving the first data file to the target system; if the second preset data extraction method is used for data extraction, perform data extraction on the source system, and save the extracted data file to the target system. The invention realizes data table partition extraction, improves data extraction efficiency and reduces data extraction errors.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data extraction method and device. Background technique [0002] With the development of Internet technology, more and more systems need to carry out data transmission and application, which requires the data of some systems to be extracted and imported or exported to the corresponding destination system. [0003] Existing data extraction solutions are usually implemented through the following steps: identify the range of source system data tables that need to be exported; write export and import statements, export DMP files and transfer them to the target system, or import DMP files. The entire processing flow of the existing data extraction scheme needs to be controlled and executed by the operator, which will result in low data extraction efficiency due to manual intervention. Moreover, the export and import process of a large number of data tables is prone to error...
