活动之间通过顺序流(sequence flow)连接,在流程图中是一个有向箭头。在执行流程实例时,执行(execution)会从启动事件沿着顺序流流向下一个活动。 离开排他网关(带有X的菱形)的顺序流很特别:都以表达式(expression)的形式定义了条件(condition) 。当流程实例的执行到达这个网关时,会计算条件,并使用第一个计算为true的...
To support parallel execution of different tasks in the package, Integration Services uses two properties: MaxConcurrentExecutables and EngineThreads.

For example, you might create five data flows, each copying data from a flat file into a different dimension table in a data warehouse star schema. However, the data flow engine determines order of execution when there are multiple data flows within one data flow task. Therefore, when order...
