Abstract

The invention discloses a data query method and device based on a global data dictionary and electronic equipment. The method comprises the steps of capturing data table information and field information from heterogeneous data sources regularly; enabling the data table information to cover the first data table, and enabling the field information to cover the second data table; respectively acquiring remark information and priority information of data tables and fields in each heterogeneous data source; storing data tables in the heterogeneous data sources and remark information and priority information of fields in the third data table and the fourth data table respectively; and querying from the global data dictionary according to query information input by a user, and displaying target data according to priority information in the global data dictionary. According to the invention, data tables and fields in different heterogeneous data sources can be quickly queried through the global data dictionary; and multi-azimuth query of names, annotations, types, remarks and the like of data tables and fields is supported.

Description

technical field [0001] The present invention relates to the technical field of data development, in particular to a data query method, device, electronic equipment and computer-readable medium based on a global data dictionary. Background technique [0002] Under the technological innovation represented by cloud computing, data has penetrated into every industry and business function area today, becoming an important factor of production, and big data development has also emerged as the times require. [0003] In the process of big data development, data information is scattered and stored in different heterogeneous data systems (such as hive, mysql, etc.). For a data requirement, such as "order" data, it needs to be queried in different heterogeneous systems, and with the increase of data volume, the data table has reached the order of 3000, and the fields of the table have reached the order of 43000 many. This results in complex data query and low query efficiency in het...
