What's the difference between domain model and conceptual model

Question

According to wikipedia they seem to be the same thing, but they each have different pages.

Domain Model

Conceptual Model

On the conceptual model page it says these two things:

A Conceptual model in the field of computer science is also known as a domain model.

a conceptual model represents 'concepts' (entities) and relationships between them.

But on the domain model page it says

A domain model in problem solving and software engineering is a conceptual model of all the topics related to a specific problem. It describes the various entities, their attributes, roles, and relationships, plus the constraints that govern the problem domain.

Are they actually the exact same thing?

Answer 1

Domain model-Conceptual model has different meanings in different context.

But in Object Oriented Analysis context they are same

A domain model is a visual representation of conceptual classes or real-situation objects in a domain [MO95, Fowler96]. Domain models have also been called conceptual models (the term used in the first edition of this book), domain object models, and analysis object models.[ page 134]
