title: What's the difference between domain model and conceptual model
body: <p>According to wikipedia they seem to be the same thing, but they each have different pages.</p>
  
  <p><a href="http://en.wikipedia.org/wiki/Domain_model" rel="noreferrer">Domain Model</a></p>
  
  <p><a href="http://en.wikipedia.org/wiki/Conceptual_model_%28computer_science%29" rel="noreferrer">Conceptual Model</a></p>
  
  <p>On the conceptual model page it says these two things:</p>
  
  <p><code>A Conceptual model in the field of computer science is also known as a domain model.</code></p>
  
  <p><code>a conceptual model represents 'concepts' (entities) and relationships between them.</code></p>
  
  <p>But on the domain model page it says </p>
  
  <p><code>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.</code>  </p>
  
  <p>Are they actually the exact same thing? </p>
