Answer 1

A class diagram is an illustration of the relationships and source code dependencies among classes in the Unified Modelling Language (UML). In this context, a class defines the methods and variables in an object, which is a specific entity in a program or the unit of code representing that entity.

In this case there are number of classes such as Doctor, Patient, Receptionist, Hospital,Clinic, Beds, Ward, Test, Checkup_Room, Waiting_Room, Receptionist_Desk,File, and Employee_Admin.

The first division of Box represent Class Name, The middle division represents Attributes and Last division represents functions.
