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:
“The ladies understood each other, in the careful way that ladies do once they understand each other. They were rather a pair than a couple, supporting each other from day to day, rather a set of utile, if ill-matched, bookends between which stood the opinion and idea in the metaphorical volumes that both connected them and kept them apart.”
—Alexander Theroux (b. 1940)
“No domain of nature is quite closed to man at all times.”
—Henry David Thoreau (18171862)
