Domain Definition Values

Domain of a function.

Domain definition values. The set of all possible input values commonly the x variable which produce a valid output from a particular function. Domain is a very popular term used in computer and information technology. For instance the natural domain of square root is the non negative reals when considered as a real number function.

The rule for determining the domain boundary may be as simple as a data type with a list of possible values. For example the range that applies to certain data types. Within a google sheet the list of possible values that the user has designated for a specific column are that column s domain.

The most basic data value domains are the simple data types themselves since they possess these characteristics. The rule for determining the domain boundary may be as simple as a data type with an enumerated list of values. In its simplest form the domain is all the values that go into a function and the range is all the values that come out.

The output values are called the range. Definition of domain domain. When the function f x x2 is given the values x 1 2 3 then the domain is simply those values 1 2 3.

Users generally do not know or misinterpret the domain keyword meaning. In data management and database analysis a data domain refers to all the valid values which a data element column may contain. The domain can be used in different areas of computer science.

A domain in general computer terminology is also the range of values that belong to a specific attribute. But in fact they are very important in defining a function. More formally a data value domain definition is composed of a domain name a set of rules that describe the set of values that belong to a restriction set and a description of the meaning associated with that set.
