| Abstract: | 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. |
