2. Domain of a function - Wikipedia

   en.wikipedia.org/wiki/Domain_of_a_function

   The term domain is also commonly used in a different sense in mathematical analysis: a domain is a non-empty connected open set in a topological space. In particular, in real and complex analysis , a domain is a non-empty connected open subset of the real coordinate space R n {\displaystyle \mathbb {R} ^{n}} or the complex coordinate space C n ...

3. Data domain - Wikipedia

   en.wikipedia.org/wiki/Data_Domain

   In data management and database analysis, a data domain is the collection of values that a data element may contain. The rule for determining the domain boundary may be as simple as a data type with an enumerated list of values. [1] For example, a database table that has information about people, with one record per person, might have a ...

4. Function (mathematics) - Wikipedia

   On the other hand, if a function's domain is continuous, a table can give the values of the function at specific values of the domain. If an intermediate value is needed, interpolation can be used to estimate the value of the function. For example, a portion of a table for the sine function might be given as follows, with values rounded to 6 ...

   Principal ideal domain, an integral domain in which every ideal is principal; Unique factorization domain, an integral domain in which every non-zero element can be written as a product of irreducible elements in essentially a unique way; Domain of a function, the set of input values for which the (total) function is defined

6. Dimension (data warehouse) - Wikipedia

   en.wikipedia.org/wiki/Dimension_(data_warehouse)

   A conformed dimension is a set of data attributes that have been physically referenced in multiple database tables using the same key value to refer to the same structure, attributes, domain values, definitions and concepts. A conformed dimension cuts across many facts.

7. Attribute domain - Wikipedia

   en.wikipedia.org/wiki/Attribute_domain

   In computing, the attribute domain is the set of values allowed in an attribute. [1] For example: Rooms in hotel (1–300) Age (1–99) Married (yes or no) Nationality (Nepalese, Indian, American, or British) Colors (Red, Yellow, Green) For the relational model it is a requirement that each part of a tuple be atomic.
