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:
“I concluded that I was skilled, however poorly, at only one thing: marriage. And so I set about the business of selling myself and two children to some unsuspecting man who might think me a desirable second-hand mate, a man of good means and disposition willing to support another man’s children in some semblance of the style to which they were accustomed. My heart was not in the chase, but I was tired and there was no alternative. I could not afford freedom.”
—Barbara Howar (b. 1934)
“In the domain of Political Economy, free scientific inquiry meets not merely the same enemies as in all other domains. The peculiar nature of the material it deals with, summons as foes into the field of battle the most violent, mean and malignant passions of the human breast, the Furies of private interest.”
—Karl Marx (1818–1883)
