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. The MaxConcurrentExecutables Property The MaxConcurrentExecutables property is a property of the package itself. This property defines how many tasks can ...
Configure the Package for Parallel Execution Parallel execution improves performance on computers that have multiple physical or logical processors. To support parallel execution of different tasks in the package, Integration Services uses two properties:MaxConcurrentExecutablesandEngineThreads. ...

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...
