the part of the systems who are involved in some activity as actors.
Class Diagrams are a part of designing proess. After coming up with use cases of the system, we take each use case and come up with the
classes that we need to perform that functionality. Each class will have Class Name, Attribues and Operations associate with it.

- Each class should have well defined responsibilities
- These responsibilities should be cohesive i.e. the system as a whole looks sensible and looks together.
