Connect Components with Paths
You construct the data flow in a package on the design surface of the Data Flow tab in the SSIS Designer. If a data flow contains two data flow components, you can connect them by connecting the output of a source or transformation to the input of a transformation or destination. The connector between two data flow components is called a path.
The following diagram shows a simple data flow with a source component, two transformations, a destination component, and the paths that connect them.
After two components are connected, you can view the metadata of the data that moves through the path and the properties of the path in Data Flow Path Editor. For more information, see Integration Services Paths.
You can also add data viewers to paths. A data viewer makes it possible to view data moving between data flow components when the package is run.
