仿真数据收集中的实时数据库技术研究

Research of Real-time Database Technology in Data Collection of Simulation

研究了实时仿真应用系统中的数据库技术。为实现仿真中数据收集、存储和事务调度的实时性,满足对所收集数据的实时使用需求,提出了一种新的稀疏索引技术。该技术在不影响数据收集任务的前提下,可以提供对所收集数据的高效查询。通过比较实验,验证了实时数据收集系统的可行性和有效性。

Database technologies used in real-time simulation systems were studied. In order to implement the data collection,data storage and transaction scheduling of simulation in a real-time manner, and to satisfy the run-time use requirement to the collected data, a new sparse index technology was provided. The index could improve the efficiency of run-time query without affecting the data collection tasks. Theavailability and efficiency of the real-time data collection system are proven by comparison experiments.
