Abstract

The invention provides a query processing method and device for a data warehouse. The method includes: detecting the preset query processing conditions of the data warehouse; when it is detected that the preset query processing conditions of the data warehouse have been met, processing the non-immediate demand queries. The device includes: a detection module and a processing module. The solution provided by the embodiment of the present invention effectively solves the problem in the prior art that the data warehouse cannot quickly execute other queries during the ETL process, and realizes dynamic optimization of query processing.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data processing, and in particular, to a query processing method and device for a data warehouse. Background technique [0002] A data warehouse (Data Warehouse, referred to as: DW) is a structured data environment of a decision support system (Decision Support System, referred to as: DSS) and an online analysis application data source. Data warehousing studies and solves the problems of obtaining information from databases. The characteristics of data warehouse are subject-oriented, integrated, stable and time-varying. In the existing technology, TERADATA is the world's largest enterprise-level data warehouse manufacturer, and its data warehouse products have been extremely influential in various industries. [0003] The characteristics of data warehouse construction and use determine that its daily data extraction, transformation and loading (Extraction Transformation Loading, re...
