Abstract

Recently object-oriented database technology has started to gain the attention of researchers in real-time database systems. This paper investigates major issues in designing semantic-based concurrency control for object-orient database systems supporting real-time applications, and describes an approach to solving those problems in an efficient way. This approach depends on the notion of affected-set of operations to determine operation compatibilities, and employs concurrency control algorithms augmented with priority-based conflict resolution schemes. With this method, it is impossible to manoeuvre the trade-off between logical and temporal consistency constraints in determining operation compatibilities, because the method deals with the two separately in different dimensions. However, this approach significantly lessens the complexity of the compatibility relation construction process, and can easily apply results from previous research on semantic-based concurrency control for object-oriented databases and on priority-based concurrency control for real-time database systems.<>

支持实时应用的面向对象数据库系统的基于语义的并发控制

近年来，面向对象数据库技术开始受到实时数据库系统研究人员的关注。本文研究了面向实时应用的面向对象数据库系统中基于语义的并发控制设计中的主要问题，并描述了一种有效解决这些问题的方法。这种方法依赖于受影响操作集的概念来确定操作兼容性，并使用并发控制算法和基于优先级的冲突解决方案。使用这种方法，在确定操作兼容性时不可能在逻辑和时间一致性约束之间进行权衡，因为该方法在不同的维度上分别处理这两者。然而，这种方法大大降低了兼容性关系构建过程的复杂性，并且可以很容易地应用先前在面向对象数据库的基于语义的并发控制和实时数据库系统的基于优先级的并发控制方面的研究成果。
