Abstract

The invention discloses a fusion query method and device of heterogeneous multi-source data, and relates to the field of big data. The method includes: receiving a data-source query request, and confirming connection parameters, which correspond to data sources, in a data model according to a query format; determining a data query adapter and data sources corresponding to the data-source query request according to types of the data sources and storage manners of the types of the data sources in a data memory; optimizing query fields in the query format according to a data-source association manner and screening conditions in the data-source query request, and obtaining first query results from the data memory according to the optimized query fields; and carrying out association fusion on the first query results according to data-source association fields and data-source association parameters in the data-source query request to obtain second query results.

Description

technical field [0001] The present invention relates to the field of big data, and more specifically relates to a heterogeneous multi-source data fusion query method and device. Background technique [0002] With the development of the Internet of Things and big data, the scale of data is growing rapidly, and the data structure is diverse. Data is providing more and more important value. The integration and analysis of heterogeneous and multi-source data is also receiving more and more attention. Related Methods and technologies are constantly evolving at a rapid pace. [0003] Currently, there are a variety of heterogeneous and multi-source data fusion analysis technologies and methods, such as open source Pentaho, various commercial BI software, and IT business systems independently developed by enterprises. Existing technologies still have great limitations in the visual analysis of big data, and the problems mainly focus on several aspects: 1) Existing BI software does ...
