Abstract

The invention provides a data extraction method, a data extraction device, a computer readable medium and electronic equipment, and relates to the technical field of data processing. The data extraction method comprises the following steps: acquiring a non-empty field set of a database and a plurality of data records in each data table in the database; determining a target field contained in each data record according to a non-empty field value contained in each data record; and determining a target data record from the plurality of data records according to the target field and the non-empty field set contained in each data record, and determining the target data record as to-be-extracted data of the database. According to the data extraction method disclosed by the invention, the consistency of the samples can still be ensured under the condition that fewer samples are extracted, so that computing resources are saved, and the extraction effectiveness is improved.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular, to a data extraction method, a data extraction device, a computer-readable medium, and electronic equipment. Background technique [0002] Database is an important tool for storing and managing data, and any Internet technology cannot do without the support of database. When using data from different sources and with different structures, it is necessary to structure the data to obtain a standard data model with a unified and standardized structure, so that the database can be used to process business data. [0003] When each original data is converted to a standard data model, it usually does not involve all types of standard data results, and the converted results can only be a subset of standard data. For example, through mapping and association, the original data can be filled into the relevant fields of several business tables of the standard data model, ...
