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:
“Not until the advent of Impressionism does the repudiation of principles set in which opened the way for the burlesque parade of the fashionable and publicity-crazed modernities of our century.”
—Johan Huizinga (18721945)
“You are the harvest and not the reaper
And of your domain another is the keeper.”
