基于替代/补偿的实时事务模型

Real-Time Transaction Model Based on Alternative/Compensate

嵌入式实时数据库系统常常在无人工干预的情况下运行,因此必须具备较高的可靠性。论文扩展基于替代的实时事务模型,使实时事务支持补偿,将替代与补偿有机结合,从不同侧面提高系统可靠性,论文还分析了支持替代/补偿的实时事务的特点,以及替代和补偿对系统可靠性的系统影响。

Embedded real-time database systems must has high reliability because it usually run without human inter-fere.The paper expands real-time transaction model based on alternative to support compensate.It combines alternative with compensate to enhance system reliability.The paper analyzes features of transactions which is based on alternative and compensate.Otherwise,the authors discuss what alternative and compensate effects on reliability.
