Abstract

The invention discloses a database access method and a middleware. The method comprises the steps that a call request sent by an application program and with respect to a universal function interfaceis received, wherein the call request includes parameter information of a target database; according to the parameter information, database accessing instructions corresponding to parameters are determined, wherein the instructions are included in a command statement of the universal function interface; the instructions are parsed, and the operation accessing the target database is executed according to instruction parsing results; the execution result of the accessing operation is sent to the application program so as to solve the problems of development work repetition and low development efficiency of database access of a programmer at present.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a database access method and middleware. Background technique [0002] A relational database is a database based on a relational model, which uses mathematical concepts and methods such as set algebra to process data in the database. Various entities in the real world and various links between entities are represented by relational models. The relational model was first proposed by Edgar Codd in 1970, and it cooperates with "Codd's twelve laws". Although there are some criticisms of this model today, it is still the traditional standard for data storage. The standard data query language SQL is a language based on relational databases. This language executes the retrieval and operation of data in relational databases. The relational model consists of three parts: relational data structure, relational operation set, and relational integrity constraints. [0003] In traditional sy...
