I'm working on a college exercise and have the following question:
What is the domain of the "country" table?
My understanding of domain is that it defines the possible values of an attribute.
This means that the table "country" doesn't have a domain, but the various attributes in the table "country" have their own domains.
For example the attribute "SurfaceArea" has the domain FLOAT(10,2)
and the attribute "Name" has the domain CHAR(52)
.
Is this correct?
