An Approach for ORDBMS Architecture
对象关系数据库管理系统体系结构的研究

In last years,with the Object-Oriented Programming popular and the field of database application extended, many DBMS manufacturers integrate the object model into traditional Relational Database Management Systems (RDBMSs)one after another,in order to meet the needs for complex engineering applications. This paper firstly gives a total remark on the reason for the prevalence of the Object-Relational Database Systems (ORDBMs)and on the benefit of ORDBMSs comparing with RDBMSs and Object Oriented Database Management Systems(OODBMSs) ,then introduces an approach for ORDBMS architecture which integrates the Java class library into ORDBMS metadata repository.
