Domain Model
A Domain Model is a high-level model that helps create structured representations (that support domain understanding and problem solving tasks).
- AKA: Problem Domain Model, Domain Knowledge Model, Domain-Specific Model.
- Context:
- It can typically capture Domain Knowledge through concept organization.
- It can typically represent Domain Entity through attribute definition.
- It can typically define Domain Relationship through entity interaction.
- It can typically enforce Domain Constraint through integrity rules.
- It can typically guide Domain Analysis through conceptual framework.
- It can often support System Development through model-driven engineering.
- It can often facilitate Knowledge Transfer through domain documentation.
- It can often enable Domain Reasoning through logical structure.
- It can often improve Stakeholder Communication through shared understanding.
- ...
- It can range from being a Simple Domain Model to being a Complex Domain Model, depending on its domain complexity.
- It can range from being an Informal Domain Model to being a Formal Domain Model, depending on its formalization level.
- It can range from being a Static Domain Model to being a Dynamic Domain Model, depending on its behavioral scope.
- ...
- It can be produced by a Domain Modeling Task with domain analysis capability.
- It can have Validation Methods through domain expert review.
- It can have Evolution Processes through domain knowledge updates.
- ...
- Example(s):
- Software Domain Models, such as:
- Enterprise Models, such as:
- System Models, such as:
- Knowledge Domain Models, such as:
- Specialized Domain Models, such as:
- ...
- Software Domain Models, such as:
- Counter-Example(s):
- Common Sense Models, which lack domain specificity.
- General Purpose Models, which are not domain specific.
- Implementation Models, which are too low level.
- Abstract Models, which lack domain context.

- In software engineering, a domain model is a conceptual model of the domain that incorporates both behavior and data.[1] [2] In ontology engineering, a domain model is a formal representation of a knowledge domain with concepts, roles, datatypes, individuals, and rules, typically grounded in a description logic.

- A domain model in problem solving and software engineering can be thought of as a conceptual model of a domain of interest (often referred to as a problem domain) which describes the various entities, their attributes and relationships, plus the constraints that govern the integrity of the model elements comprising that problem domain.
