实时数据库系统的面向对象数据模型及调度策略研究

Research on object\|oriented data model and schedule policy of real\|time database system

分析了实时数据库系统中的数据和事务的特性． 提出了一种实时面向对象的数据模型，它充分考虑了实时数据库系统对数据和事务的逻辑及时间一致性的要求． 依据这种数据模型，可以设计出各种合适的并发控制协议及事务调度策略。

This paper analyses the characteristics of data and transactions in real\|time database system and gives a real\|time object\|oriented data model. The model can meet the logical and temporal consistency of data and transactions in real\|time database system. Various kinds of proper concurrency control protocol and transaction schedule policies can be developed based on this model in order to improve the performance of real\|time database system.
