Object-oriented data bank access method and system

Abstract

This invention discloses an access method and a system for database facing objects, in which, said method includes: analyzing requests of objects to obtain accessed database list names, at least one access field, a condition field and a condition comparing value, generating key assignments based on the analyzed result including database list names, access fields and access condition fields, looking for parameterized SQL sentences corresponding to said key assignments and generating parameterized SQL sentences and storing them if they are not found out and setting the condition comparing value to a request parameter, if they are found out, then the request parameter is assigned to execute related access operation, in this invention, similar object requests use a same parameterized SQL sentence so as to reduce time cost for editing and generating SQL sentences many times.

Description

technical field

[0001] The invention relates to database access technology, in particular to an object-oriented database access method and system. Background technique

[0002] Object Relationship Mapping (ORMapping for short) is a technology that maps a database table to a class in an object-oriented system, and each record in the table corresponds to a specific object of the class. Through this technology, an object-oriented approach can be used in the process of software development to deal with database-related parts, such as adding, modifying, and deleting records.

[0003] Object-oriented databases organize data into objects, objects can have attributes, and each attribute is also an object. In ORMapping technology, SQL (Structured Query Language, Structured Query Language) statements for database access operations will be generated according to requests (generally divided into operations such as adding records, deleting records, and querying records). The process of...
