Abstract

The invention discloses a data query method and device for multi-source heterogeneous data, a computer readable storage medium and equipment, and the method comprises the steps: analyzing a received structured query statement for the multi-source heterogeneous data, determining a to-be-queried sub-data source and query semanteme, generating a query statement suitable for the type of the sub-data source, querying each sub-data source to obtain corresponding sub-target information, and integrating the obtained sub-target information into target information according to query semantics, so that the query of multi-source heterogeneous data can be achieved by using one query interface, the query interface of data query is simplified, therefore, query semantic maintenance of various data source types is avoided, the method has very high applicability to multi-source heterogeneous data, and the reusability of data query codes is remarkably improved. The query efficiency is effectively improved, and computing resources and storage resources are saved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data query method, device, computer-readable storage medium and equipment for multi-source heterogeneous data. Background technique [0002] With the rapid development of big data technology, databases with various structures have also been widely used. The data systems of many enterprises are also built based on databases of various structures. For example, data systems with high immediacy requirements can be constructed based on relational database architectures such as mysql, oracle, sqlServer, and mongo; while data systems with general immediacy requirements can be constructed based on hive, presto, spark, and hadoop database architectures to build. Data sources that can configure multiple data structures in the data system meet the needs of enterprises for data sources to a large extent. [0003] However, in the current multi-data source data system base...
