Hi,

Inorder to describe the structure of a system a class diagram is used.There are Domain model class diagram and Design Class Diagram.The difference between them are given below:

Domain Model Class Diagram	Design class diagram
1.Representation of real world	1.Representation of software definition
2.Identify relevant concepts and ideas of domain	2.Identify the specification of software classes
3.It does not consist of methods of class	3.It consist of methods of each class
