Program Plan Intro
Object Oriented Data Model (OODM):
An Object Oriented Data Model is used in logical
Class:
- A class is a collection of data members and member functions, which are used to represent the overall structure of the project.
- The objects are created to access the data members and member functions of the class.
- The process of creating a new class from the existing class is called as inheritance. Here, the existing class is named as super class and the newly created class is named as sub class.
Object:
- The variable for this defined class is called the object.
- It is also called as instance of a class.
- It is a unit of code which is derived from the processes.
- It is an instance of the class which has its own procedures for the execution.
