面向对象数据库管理系统中的事务管理

一、引言事务是进行一致可靠计算的基本单元,由一系列原子操作组成。事务满足ACID准则;原子性、一致性、隔离性、持久性.在数据库管理系统(DBMs)中。

In the case of object-oriented database management systems(OODBMS),the traditional transaction management techniques are not sufficient and more powerful transaction models and more flexible correctness criteria need to be developed.In this paper,the transaction management requirements of OODBMS from“advanced”applications are identified.Then adopt history serializ- ability to classify correctness criteria and classify transaction models along two dimensions;the transaction structure and the object structure.At last,we evaluate both the correctness criteria and transaction models comprehensively.
