The Application Designer session concept knows one level below the Application Designer session: the Application Designer subsession. Adapter objects are living inside one subsession - and there can be multiple subsessions within one session.

Let us approach the subsessions by a practical example:

In the diagram, the Application Designer demo workplace is shown. Inside the workplace, three activities have been opened. The "Address Management" application is currently active. In addition, the workplace is also running.

See the next section Application Designer Subsession - Application Designer Adapter Objects for further information on this example.
