摘要
讨论了数据网格的背景以及目前国内外的研究状况。并根据应用的需求,提出了数据网格中面向服务的事务管理观点。定义了服务事务在数据网格体系结构中的位置、功能和实现方案,阐述了原子事务和业务事务两类事务的实现协议,最后以一个原子事务的例子说明了一个服务事务的执行过程。
Data grid is a kind of distributed database storage system under grid environment. This paper firstly introduces the background of data grid and the survey of research on this field.To meet the needs of applications, it points out the concept of the service-oriented transaction management in data grid environment. Then it gives the overview of data grid architecture with service transactions, and describes the function, implementation of service transactions. Two types of ,service transactions with protocols are discussed to explain the ideas which are atomic transactions and business transactions. An example of atomic transaction is given to demonstrate the execution process of service transaction at last.
