Problems solved by technology

Although the relational database implements a complete set of relational description language, which can meet the definition of query, aggregation, and modification, but this definition cannot be migrated to nosql, that is to say, it cannot be migrated to other types of databases.
Therefore, at present, the industry is still unable to realize data query across data sources, and the development of microservices still has bottlenecks in data query and tracking

Abstract

The invention provides a data query method and system. The method comprises the steps of obtaining data query request information, wherein the data query request information is used for requesting toquery different types of associated data; analyzing the data query request information, and determining each database where the requested data is located; and respectively calling the data source accessor corresponding to each database where the requested data is located, and reading the data requested by the data query request information from each database where the requested data is located. According to the processing process, associated data query across different types of databases is achieved, namely cross-data-source data query is achieved, and the bottleneck of micro-service data reading can be eliminated by applying the technical scheme to a micro-service system.

Description

technical field [0001] The present application relates to the technical field of data processing, and more specifically, to a data query method and system. Background technique [0002] As microservices become more and more common, a piece of data, or a series of related data, will be distributed and stored in different data sources, such as mysql, redis, mongodb, elasticsearch and other databases. In this case, data query and data tracking become the key to business development. [0003] At present, existing solutions in the industry mainly model data in the case of isomorphic databases (referring to one type of database, such as both based on mysql, or all based on redis), especially relational databases. Although relational databases implement a complete set of relational description languages ​​that can satisfy the definitions of query, aggregation, and modification, such definitions cannot be migrated to NoSQL, that is to say, they cannot be migrated to other types of ...
