主动实时数据库复杂事务的管理

Transaction Mangagement in Active Real[CD*3〗Time Database Ststems

讨论了嵌套事务模型在主动实时数据库中的应用，提出了一种管理主动实时数据库嵌套事务的策略和方法．允许子事务的不同步执行使最紧急的事务尽可能快地执行，子事务的独立提交或中止可将失败影响局限在局部范围内。

This paper discusses the nested transaction model in the Active RealTime Database Systems.We present a method for managing the nested transaction in ARTDS.Allowing the subtransactions to execute asynchronously can make the most urgent transaction run as fast as possible and the subtransactions which can commit or abort independently also limit the effects of the failure in a local area that will satisfy the deadline of transactions.
