Viewing Package Objects
In SSIS Designer, the Package Explorer tab provides an explorer view of the package. The view reflects the container hierarchy of the SQL Server 2005 Integration Services (SSIS) architecture. The package container is at the top of the hierarchy, and you expand the package to view the connections, executables, event handlers, log providers, precedence constraints, and variables in the package.
The executables, which are the containers and tasks in the package, can include event handlers, precedence constraints, and variables. Integration Services supports a nested hierarchy of containers, and the For Loop, Foreach Loop, and Sequence containers can include other executables.
If a package includes a data flow, the Package Explorer lists the Data Flow task and includes a Components folder that lists the data flow components.
From the Package Explorer tab, you can delete objects in a package and access the Properties window to view object properties.
The following diagram shows a tree view of a simple package.
