| 摘要: |
| 针对嵌入式数据库系统的实时性和高可预见性,提出了基于功能替代的事务模型.该模型改善了实时事务对动态实时环境的应变能力.由于受功能替代性的影响,事务调度分为内部调度和外部调度,提高了系统的成功率.研究了实时事务的可调度性分析,并给出了相应的内部调度策略,最后作出模拟性能分析. |

| Abstract: |
| A transaction model is proposed based on function alterative characteristic, which improves the ability of transaction suiting for real-time environment. As the characteristic, transaction schedule is divided into interior schedule and exterior schedule, which increases the systems success ratio. The other main contribution is to provide more abundance transaction semantic for embedded database systems. |
| Key words: database system embedded system transaction schedule |
