| 摘 要： | 给出了面向对象数据库系统的一种并发控制机制－ＯＯ－Ｌｏｃｋｉｎｇ，分析了面向对象数据库系统中事务模型的两个方面：操作和对象，并利用事务的操作和操作对象对语义来提高并发度，讨论了复杂对象和多继承类层次上的封锁技术，提出了三种锁：类锁、对象锁和条件锁，较好地描述了操作之间的冲突性和可交换性。部分技术已用于ＣＩＭＳ环境下面向对象数据库系统ＦＯＯＤＢ２．０的实现的。

| Abstract: | n this paper, aconcurrency control mechanism in object-oriented database systim,analyze two aspects of transaction model:operations and objects,and exploit semantics of operations and objects to enhance concurrency, also discuss technuques for locking objects and classses in detail presented. Three kinds of locks are given: class lock,condition lock, and object olck, which can describe confliction and commutativity between operations properly. Some of these techniques had been used in OODBM FOODB2. 0 in CIMS environment. |
