OODBMS中的数据一致性研究

Research on Data Coordinating in OODBMS

面向对象的数据库OODB是把面向对象的方法结合关系数据库所产生的新一代数据库，关系数据库具有完善的规范化理论、关系资料理论，面向对象的技术具有极强的描述客观世界的能力，二者的结合使得OODB具有强大的描述客观世界的功能。但面向对象技术的复杂性使得面向对象的数据库管理系统OODBMS在维护资料的一致性方面也非常复杂，论文基于关系数据库理论的资料一致性理论，从对象属性的一致性、对象间的一致性和日志文件三方面探讨了如何维护OODB的资料一致性。

： The Object Oriented Data Base is new database which is combined the methodology of Object－Oriented into Relational Database，the Relational Database has the theory of normalized and relational datas at the same time the methodology of Object－Oriented has the powerful capability of description the objective world，so the Object Oriented Data Base has the powerful capability of description the objective world．The complexity of maintaining the data coordinating in Object Oriented Data Base Management System is due to the complexity of the methodology of Object－Oriented．This paper proposes how to coordinate data by coordinating the object′s attribute，object and log file which are based on the theory of relational database．
