| Abstract: | This paper analyzed transaction scheduling strategies for parallel database system and real time database in common use and put forward a transaction scheduling algorithm for parallel real time database based on SN architecture. The algorithm possessed high concurrency of parallel database and real time property of real time database system. It was so flexible and the different practical demands can be satisfied by changing the value of parameters. |
