Object-role model overview

This ORM diagram sample presents object-role model overview. It was designed on the base of the Wikimedia Commons file: Object-Role Model Overview.jpg. [commons.wikimedia.org/wiki/File:Object-Role_Model_Overview.jpg] "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. ... More recently ORM has been used to model business rules, XML-Schemas, data warehouses, requirements engineering and web forms." [Object-role modeling. Wikipedia] The ORM diagram example "Object-role model overview" was designed using ConceptDraw PRO software extended with ORM Diagrams solution from Software Development area of ConceptDraw PRO Solution Park.
