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:
“A wise man should order his interests, and set them all in their proper places. This order is often troubled by greed, which puts us upon pursuing so many things at once that, in eagerness for matters of less consideration, we grasp at trifles, and let go things of greater value.”
—François, Duc De La Rochefoucauld (1613–1680)
“In the domain of art there is no light without heat.”
—Victor Hugo (1802–1885)
