There are global transactions and local transactions in the grid database.The serializability of global transaction is very important in transaction management.
网格数据库中的事务也存在全局事务和局部事务之分,对全局事务要保证得到正确的执行结果,其串行化是关键。

Firstly, the definition of cooperative transactions is given and the states of them are specified. Secondly, the dependencies among cooperative transactions and those between cooperative transactions and outside environments are specified in terms of states of cooperative transactions. Finally, the serializability correctness criterion for the presented model is specified by state dependencies of cooperative transactions.
首先给出了协同事务的定义,并描述了协同事务的状态,然后从协同事务的状态角度刻画协同事务之间、协同事务与外部环境之间的复杂依赖关系,最后用协同事务的状态依赖描述了可串行化正确性准则。

Global transaction management Global transaction management consists of global serializability, global atomicity and recovery, global deadlock checker, etc. In distributed data resources management, the complexity of local data sources increases the difficulty of global transaction management.
分布数据资源管理中的全局事务管理通过对事务管理的关键问题的分析,针对分布数据资源管理中数据源在事务处理能力中的巨大差异,提出了给每一个局部数据源包装器添加一些事务处理的功能,让包装器针对特定数据源的具体情况完成部分全局子事务的并发控制和恢复管理,使得在全局管理层可以使用二阶段锁进行并发控制和使用二阶段提交进行事务恢复,并使用超时法进行死锁检测,从而达到分数据资源的全局事务管理。

DDMRA only recoveries incorrupted data items by malicious transactions to avoiding re-excution of innocent operations while transaction dependency methods undo-redo all operations of malicious transactions. In BDDMRA, benign blind writes can write bad data items to normal state thus corresponding malicious operations are not necessary to undo-redo and it will speed up recovery process.
DDMRA算法通过仅仅将恶意事务篡改的数据恢复到正常版本而无需全部&撤销-重做&事务中的所有操作从而避免了无辜操作的重复执行;BDDMRA算法分析了存在盲写事务条件下基于数据依赖的恶意事务恢复方案,善意的盲写事务可以将已破坏的数据恢复到正常状态,无需&撤销-重做&相关恶意操作,从而加快了恢复过程。

A new OLAM task/transaction model based on AOR-DAG also presents in this paper, which can describes complex OLAM tasks and transactions, implies the control stream and the data stream.
论文在对OLAM任务的特点和任务类别的分析的基础上,提出了一种新的OLAM任务/事务模型,这个模型通过AOR-DAG图来表示复杂的OLAM任务和事务,其中同时蕴涵了事务的控制流和数据流,是OLAM事务优化和调度的依据。

Several new approaches of transaction management are proposed as follow: A design transaction model is proposed to support the nested transaction structure, resumable execution, the management of flowing transaction, cooperation of transaction with respect to data, and dynamic restructure of the transaction.
该模型支持嵌套的事务结构,长事务的可持续执行,流程化事务的管理,事务间关于数据对象的合作以及事务的动态重构。
