Abstract

This paper provides an overview of Object-Role Modeling (ORM), a fact-oriented method for performing information analysis at the conceptual level. It provides both a graphical and textual languages and a procedure which guides the use of the languages. The article is structured in two main parts. The first part presents an overview of ORM along a real example, while the second part of the article makes a comparison between ORM and UML from the conceptual data modeling perspective.
