"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. 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. ORM is attribute-free : unlike Entity Relationship (ER) and Unified Modeling Language (UML) models, ORM treats all elementary facts as relationships and so treats decisions for grouping facts into structures (e.g. attribute-based entity types, classes, relation schemes, XML schemas) as implementation concerns irrelevant to semantics."
