1. Introduction

This is a basic UML class diagram, which illustrates both the Checking Account and Saving Account class, and their relationships. A Class is an object's blueprint. Objects and classes are inextricably linked. We can't discuss one without discussing the other. And, because we utilize classes to generate objects, the entire objective of Object-Oriented Design is not about objects, but about classes. As a result, while a class describes what an object will be, it is not the object itself.

Classes, on the other hand, specify the types of things, whereas objects are useable instances of classes. Each Object was constructed using the same blueprints and so has the same components (properties and methods). An object is a member of a class and has states and behaviors, according to the standard definition.

2. The Usage of UML Classs Diagram

UML has primarily been utilized in the realm of software engineering as a general-purpose modeling language. It has, nevertheless, made its way into the documentation of a number of business processes and workflows. Flowcharts, for example, can be replaced by activity diagrams, which are a sort of UML diagram. They offer a more uniform approach to workflow modeling as well as a broader set of capabilities to boost readability and efficiency.
