Abstract

The invention discloses inquiry system and method of a customized database. The system comprises a WEB layer module, a service layer module, a DAO layer module and a physical layer module, wherein the WEB layer module calls the corresponding operational project function in the service layer module according to an operational project request of a user; the service layer module breaks up the corresponding operational project function into a plurality of business operations according to a calling indication of the WEB layer module and respectively calls a DAO operation method corresponding to the business operations in the DAO layer module; the physical layer module preliminarily creates an inquiry intermediate table and a public Bean class, i.e. a public affair object class, and inquires in the database according to the operational project request of the user and the preliminarily created inquiry intermediate table, and the inquired operational project result is put into the preliminarily created public Bean class. The invention realizes the real stripping of a framework layer and a data business layer in the inquiry developing process of the database and reduces the problem of difficult resource development and program maintenance.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a customized database query system and query method. Background technique [0002] At present, in the development process of the database information query system, generally for a certain project requirement, the developer needs to independently develop the corresponding interface, logic processing, and SQL statements for interacting with the database.
