Relational Domain Map and Relational Domains
A database can be split into a set of relational domains.
A relational domain is used to define a physical data structure.
A relational domain map is used to visualize the dependencies between relational domains.
Relational Domain Map
A relational domain map is an urbanization tool for physical information. It represents a set of relational domains in a particular context.

Components of a relational domain map
You can add internal and external components to a relational domain map.
The internal components are relational domains that are part of the map scope (whether they belong to the same owner element or not).
The external components are those used in the map but that are not part of the scope analyzed.
To add a relational domain to the map:
1. In the diagram insert toolbar, click the Internal Component button then click in the map.
2. Indicate the name of the relational domain and click OK.
