NET的事务控制

在分布式应用程序中，不可避免地会经常使用到事务控制。事务有一个开头和一个结尾，它们指定了事务的边界，事务在其边界之内可以跨越进程和计算机。事务边界内的所有资源都参与同一个事务。要维护事务边界内资源间的一致性，事务必须具备 ACID 属性，即原子性、一致性、隔离性和持续性。



本地事务和分布式事务

--------------------

本地事务是其范围为单个可识别事务的数据资源的事务（例如，Microsoft SQL Server 数据库或 MSMQ 消息队列）。例如，当单个数据库系统拥有事务中涉及的所有数据时，就可以遵循 ACID 规则。在 SQL Server 的情况下，由内部事务管理器来实现事务的提交和回滚操作。-NET Services in distributed control applications, will inevitably be used to control affairs. Services have a beginning and an end, they have designated border affairs, in its affairs within the borders across process and computers. Services within the borders of all resources involved with a transaction. Services to protect the resources within the borders of consistency, the Panel must possess ACID properties, that is, atomicity, consistency, isolation and sustainability. Local Affairs and the Distributed Transaction -------------------- domestic affairs of its range of single - Services could be the identification of resources data services (for example, Microsoft SQL Server database or MSMQ Message Queue). For example, when a single database system with affairs involving all the data,
