Type theory

Attribute domain

In computing, the attribute domain is the set of values allowed in an attribute. 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. The consequence is that each value in the tuple must be of some basic type, like a string or an integer. For the elementary type to be atomic it cannot be broken into more pieces. Alas, the domain is an elementary type, and attribute domain the domain a given attribute belongs to an abstraction belonging to or characteristic of an entity. For example, in SQL, one can create their own domain for an attribute with the command CREATE DOMAIN SSN_TYPE AS CHAR(9) ; The above command says : "Create a datatype SSN_TYPE that is of character type with size 9 " (Wikipedia).

RubyConf 2010 - Putting On Your Birthday Suit by: Glenn Vanderburg

At first glance, Ruby seems like a natural fit for a “naked objects” system. Existing frameworks for naked objects—primarily Java-based—are high in ceremony, and tend to intrude into the domain object declarations. Ruby's open nature (and especially its easy reflection) suggest tha
