A conceptual model can be described using various notations, such as [[Unified Modeling Language|UML]], [[Object-role modeling|ORM]] or [[Object-modeling technique|OMT]] for object modelling, or [[Information Engineering|IE]] or [[IDEF1X]] for [[Entity-relationship model|Entity Relationship Modelling]]. In UML notation, the conceptual model is often described with a [[class diagram]] in which [[class (computer science)|class]]es represent concepts, [[Association (object-oriented programming)|association]]s represent relationships between concepts and [[role type]]s of an association represent role types taken by instances of the modelled concepts in various situations. In ER notation, the conceptual model is described with an ER Diagram in which entities represent concepts, [[cardinality]] and [[optionality]] represent relationships between concepts. Regardless of the notation used, it is important not to compromise the richness and clarity of the business meaning depicted in the conceptual model by expressing it directly in a form influenced by design or implementation concerns.

This is often used for defining different processes in a particular Companycompany or Instituteinstitute.
