Set Domain

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 (1788–1824)

    No domain of nature is quite closed to man at all times.
    Henry David Thoreau (1817–1862)
