When you create a mapping, you must add one or more target definitions to it. When you drag a target definition into the Mapping Designer workspace, you add an instance of the target definition.

When you add targets to a mapping, you can include different types of targets. You can include targets of the same database type, but different database connections. You can also include both relational and flat file targets in the same mapping.

When you edit the target in the Target Designer, all instances of the target in mappings inherit the changes. Some changes might invalidate the mappings using the target.

You can configure properties for relational, file, and XML targets in a mapping.
