基于主动数据库体系的仿真实时性和交互性的实现

Implement of real-time performance and Interaction performance in the system simulation based on active mechanism database

为了适应计算机仿真系统对实时性和交互性的高要求,提出一种新的提高体系仿真实时性和交互性的方法———主动机制数据库技术。主动机制数据库动态监视后台数据库中的数据状态的变化,通过主动机制对这些数据进行管理,形成主动数据库管理系统。首先介绍了主动数据库的概念和典型的代表系统;然后从主动数据库的定义、规则的表示、规则的存储结构、规则的处理等方面详细说明了主动数据库技术的设计思想;最后以飞机控制数据库系统(FCS-DBS)为例,说明了主动机制数据库的应用。

This thesis introduces the main contents of research and development on the active-rule database system. Arimed at the high request of the System Simulation, a new approach is put forword. Namely-the technology of active rule databaseo The method can monitor dynamically data of backend corporate database and manage them, relying on the technology of active rule, then structures an active database management system. The paper first introduces the concept of ADBS. Then it discusses the design idea in detail in such topics as definition of ADBS, denotation of the rule, memory structure of the rule, disposition of the rule, etc. Finally the paper chooses a practicality application system FCS - DBS （ Flight Control System - Database system） to testify the validity of conclusion.
