Abstract

The invention provides a data access method, device, system and equipment based on a virtual database, a medium and a program product, and relates to the technical field of databases. The method comprises the following steps: receiving an SQL query request of a user layer; performing statement analysis on the SQL query request, calling a preset rule in a rule base based on a statement analysis result to decompose the SQL query request into a plurality of local query statements, and routing and distributing the local query statements to corresponding databases to obtain corresponding query data; and assembling the query data and then outputting a query result to the user layer. According to the data access method based on the virtual database, the problems that in the prior art, due to the fact that different code logics are written for different databases to complete corresponding connection and access operation, the code writing amount is large, the request end service logic is complex, and maintenance is difficult are solved.

Description

technical field [0001] The present disclosure relates to the technical field of databases, and more specifically relates to a virtual database-based data access method, device, system, equipment, medium and program product. Background technique [0002] At present, the internal logic of mainstream large-scale enterprise-level applications is becoming increasingly complex, and there are many types of databases used due to historical or upgrading reasons, such as mysql, oracle, informix, etc. If the data requester wants to implement connection and access to heterogeneous databases, it needs to write different code logic for different databases in the application to complete the corresponding connection and access operations. The amount of code writing is large, the business logic of the request side is complex, and maintenance is difficult. Contents of the invention [0003] In view of the above problems, the present disclosure provides a data access method, device, system,...
