Object Role Modeling         
<programming> (ORM) A conceptual modelling approach that pictures the application world as a set of objects that play roles (parts in relationships, which may be unary, binary or higher order). ORM provides both graphical and textual languages that enable models to be expressed naturally. For data modelling purposes, its graphical language is more expressive than ER or UML. http://orm.net/.

Object-role modeling         
Object-role modeling (ORM) is used to model the semantics of a universe of discourse. ORM is often used for data modeling and software engineering.
Natural Language Information Analysis Method         
(NIAM, or Nijssen IAM) A method for data modelling. ["Conceptual Scheme and Relational Database Design", Nijssen and Halpin, Prentice-Hall, 1989]. (1995-03-31)

Object–role modeling

Object–role modeling (ORM) is used to model the semantics of a universe of discourse. ORM is often used for data modeling and software engineering.

An object–role model uses graphical symbols that are based on first order predicate logic and set theory to enable the modeler to create an unambiguous definition of an arbitrary universe of discourse. Attribute free, the predicates of an ORM Model lend themselves to the analysis and design of graph database models in as much as ORM was originally conceived to benefit relational database design.

The term "object–role model" was coined in the 1970s and ORM based tools have been used for more than 30 years – principally for data modeling. More recently ORM has been used to model business rules, XML-Schemas, data warehouses, requirements engineering and web forms.
