LogoutA workflow is a collection of instructions provided with the Program Executor as a guideline for completing tasks and containers.
When a package is executed, a control flow usually consists of one or more tasks and containers that execute. Priority constraints, which connect the tasks and containers in a package, are used to set requirements for performing tasks in the package control flow.
There are three control flow elements that SSIS provides:
- Containers that provide structures in packages
- Tasks that provide functionality
- Precedence constraints that connect the executables in an ordered control flow
Sources and destinations that extract and load data, transformations that change and expand data, and routes that connect sources, transformations, and destinations make up a data flow. SSIS packages that produce, arrange, and operate the data flow can run the data flow task.
