Abstract

Abstract:

Due to the impedance matching of the object and the relations, the Object-Relational Mapping（ORM） is be- coming a focus of the field of software dev elopment. This paper puts forward a three-layered system architecture for object- oriented relational databases. And an O-R agent layer is added between the operation-layer and the relational database. Each layer and its analysis are discussed in detail. Finally,the validity of the model is demonstrated in practice.

Key words: object relational mapping, ORM, system model
