A domain is a named set of values. Its main application in computing science is as a specification of the possible values of variable, or—what amounts to the same—as a constraint for an attribute in a database.
Defining a domain for a set of values is essential in many computer programs. It ensures that incorrect data are left out, and is often used as a tbles. Thus, for instance, it cannot contain some integer values and some string values.
Example of code fragments that define domain sets:
int odd = {1, 3, 5, 7, 9}; String members = {"Jason", "Mary", "Bob", "Andrew"}; int ageRange; for i = 1 to 80 ageRange = i;Famous quotes containing the words set and/or domain:
“Thou shalt not set up Wordsworth, Coleridge, Southey;
Because the first is crazed beyond all hope,
The second drunk, the third so quaint and mouthy:”
—George Gordon Noel Byron (17881824)
“No domain of nature is quite closed to man at all times.”
—Henry David Thoreau (18171862)
