Building a domain model

A domain represents the set of possible values for a column. Each column
should therefore be linked to a domain, which itself is linked to a
data type.
open ModelSphere also offers domain models. There are three ways to create
this type of model:
- From the main menu choose Edit > Add > Domain model > Target system
of your choice.
- Right-click Project and choose Add > Domain model > Target system of your choice.
- In the Edit toolbar, click the Add tool
> Domain model > Target
system of your choice.
By default settings, the diagram for a domain model is displayed upon request.
With the pointer tool, select domain model in the explorer window and do Add
> Diagram. If you want to modify the default settings, see Modifying the options.
To add objects to the domain model: highlight domain model in the explorer window, then choose Edit > Add >
Domain.
You should name the domains immediately after their creation.
