An Execution Environment is a type of node that defines a set of services that support software. For example, an execution environment in the processor on a server might provide the operating system-level services needed to support a database application installed in that environment. Some typical stereotypes for an execution environment include <OS>, <workflow engine>, <database system>, and <J2EE container>.
 
Specify the Execution Environment element in the Execution Environment Specification window.  

The Execution Environment dialog box contains the following specific panes:

• Nested Nodes: lists nodes defined (nested) in the Execution Environment.
• Deployed Artifacts: an artifact or artifact instance that has been deployed to a deployment target.

You can format the Execution Environment symbol properties in the Symbol Properties dialog.
