Why They are Needed
For a site with a “product” that has many thousands of components spread across multiple ISPW Applications it might not be practical to have them all deployed to a single load library (for example). By defining a Deployment Domain to each Application, it is then possible to define a different Storage Name per Deployment Domain on the target platform and so have the components spread across a number of Storage Names (i.e. datasets).
The diagram shown in the following figure helps describe how Domains work.
