关系数据库与面向对象数据库的集成

INTEGRATE RELATIONAL DATABASE AND OBJECT ORIENTED DATABASE

本文从ＲＤＢ（ｒｅｌａｔｉｏｎａｌｄａｔａｂａｓｅ）的缺欠、ＯＯＤＢ（ｏｂｊｅｃｔｏｒｉｅｎｔｅｄｄａｔａｂａｓｅ）的不足和新的数据库应用需求３个方面指出了统一关系范型和ＯＯ范型、集成ＲＤＢ与ＯＯＤＢ的趋势，讨论了集成ＲＤＢ与ＯＯＤＢ的３种途径。

Due to limitations of RDBs(relational database), deficiencies of OODBs(object oriented database) and requirements of new applications, a new trend in database area is becoming more and more obvious that relational paradigm and OO paradigm are to be unified in the database context, and RDB and OODB are to be integrated transparently. This paper first discusses three approaches for integration of RDB and OODB, and then introduces the design of a multimedia database system TH CIMHYPER in which the authors adopt the unification approach.
