Abstract

The invention relates to a data query method and device, a server and a storage medium, and the method comprises the steps: converting a received data query request, and obtaining a converted data query request; enabling the received data query request to be a data query request for at least two data dimensions; generating a processing operation combination corresponding to the converted data query request; enabling the processing operation combination to be composed of a plurality of processing operations arranged in sequence; determining a query executor corresponding to each processing operation; executing each processing operation according to a query executor corresponding to each processing operation to obtain a data query result corresponding to the received data query request; enabling at least two of the query actuators to be used for querying the corresponding metadata from the at least two databases. By adopting the method, the purpose of obtaining the data query result corresponding to the data query request by utilizing a plurality of query actuators is achieved, and the data query processing efficiency is improved.

Description

technical field [0001] The present disclosure relates to the technical field of data analysis and query, and in particular to a data query method, device, server, storage medium and computer program product. Background technique [0002] In the OLAP (Online analytical processing, online analytical processing) analysis scenario, it is necessary to query data from different data engines and process the data obtained from the query. [0003] In related technologies, the current data query method is generally to import the data corresponding to the multi-source OLAP data engine into an OLAP data engine that supports storage, so as to indirectly support the query and analysis requirements of the multi-source OLAP data engine; however, in the data query When processing, only one main engine is actually used, and the data query methods in different data engines in the main engine are different, which makes the data query processing process more cumbersome, thereby reducing the effi...
