A '''data model''' (or '''datamodel''')<ref>{{cite web|title= datamodel - UML Domain Modeling - Stack Overflow|url= https://stackoverflow.com/a/3835214|website= Stack Overflow|publisher= Stack Exchange Inc.|access-date= 4 February 2017}}</ref><ref name="w3cxpath">{{cite web|title= XQuery and XPath Data Model

For instance, a data model may specify that the data element representing a car be composed of a number of other elements which, in turn, represent the color and size of the car and define its owner. The term '''data model''' can refer to two distinct but closely related concepts. Sometimes it refers to an abstract formalization of the objects and relationships found in a particular application ___domain: for example the customers, products, and orders found in a manufacturing organization. At other times it refers to the set of concepts used in defining such formalizations: for example concepts such as entities, attributes, relations, or tables. So the "data model" of a banking application may be defined using the entity-relationship "data model". This article uses the term in both senses.
