Abstract

The embodiment of the invention discloses a query method and device based on a heterogeneous database. The method comprises the steps: when at least two isomerous databases are connected, obtaining aquery request for the databases, wherein the query request comprises query conditions and a target database, and the query conditions are compiled by adopting a preset universal operation language; determining a target operation language adopted by a target database in the query request; converting the query condition into a query statement conforming to the target operation language; querying inthe target database by utilizing the query statement to obtain a query result; and outputting the query results.

Description

technical field [0001] The embodiment of the present application relates to the field of information processing, in particular to a heterogeneous database-based query method and device. Background technique [0002] Relying on the strong guarantee of big data, cloud computing and artificial intelligence technology, the Internet and major organizations have begun to build data centers. The data center is known as the next stop of big data, and the core idea is data sharing. First of all, it is not a platform, nor is it a system. The middle platform can be regarded as an intermediate structural layer. In the data development process, the change of the core data model is relatively slow. At the same time, the workload of data maintenance is also very large, but the speed of business innovation and the change of data requirements are very rapid. The purpose is to make up for the problem that the responsiveness cannot keep up with the development speed mismatch between data dev...
