根据维基百科，它们似乎是同一回事，但是它们各自具有不同的页面。
领域模型http://en.wikipedia.org/wiki/Domain_model
概念模型http://en.wikipedia.org/wiki/Conceptual_model_%28computer_science%29
在概念模型页面上，它说明了以下两点：
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.
但是在域模型页面上却说
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.
他们实际上是一回事吗？
