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 spirit of [William] Penn will not be stayed. You cannot set limits to such knightly adventurers. After their own day is gone their spirits stalk the world, carrying inspiration everywhere that they go and reminding men of the lineage, the fine lineage, of those who have sought justice and right.”
—Woodrow Wilson (1856–1924)
“In the domain of art there is no light without heat.”
—Victor Hugo (1802–1885)
