Conceptual model is the result of [[Object-oriented analysis and design#Analysis|object-oriented analysis]], it captures concepts in the problem ___domain. The conceptual model is explicitly chosen to be independent of implementation details, such as concurrency or data storage.

The aim of conceptual model is to express the meaning of terms and concepts used by ___domain experts to discuss the problem, and to find the correct relationships between different concepts. The conceptual model attempts to clarify the meaning of various usually ambiguous terms, and ensure that problems with different interpretations of the terms and concepts cannot occur. Such differing intepretations could easily cause the software projects that are based on the interpretation of the concepts to fail. Once the ___domain concepts have been modelled, the model becomes a [[stability (software engineering)|stable]] basis for subsequent development of applications in the ___domain. The concepts of the conceptual model can be used as basis of object-oriented design and implemented in program code, in particular as classes in object-oriented languages. The realization of conceptual models of many domains can be combined to a coherent platform.

A conceptual model can be described using various notations, such as [[UML]] or [[OMT]]. In UML notation, the conceptual model is often described with a [[class diagram]] in which [[class (computer science)|class]]es represent concepts, [[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.
