Documentation:Class diagrams

Class diagrams are a type of UML (Unified Modeling Language) diagram used to visually represent the structure and relationships of classes within a system. They play a crucial role in both the design and execution phases of a running software system.

What is a Class?

In OOP (Object-oriented Programming), a class serves as a blueprint or template for creating objects. Objects are instances of classes, and each class defines a set of attributes (data members) and methods (functions or procedures) that the objects created from that class will possess.

UML Class Notation

In class diagrams, classes are depicted as boxes, each containing three compartments:

1. Class Name: The name of the class (centered and bold).
2. Attributes: Represent data members (properties or fields).
3. Methods: Define behaviors or actions that the object can perform.

Purpose of Class Diagrams

• Provide a high-level overview of a system’s design.
• Communicate and document the structure of the software's data.

Benefits of Class Diagrams

• Serve as a blueprint for software implementation. In MDriven the implementation phase is mostly unnecessary because the MDriven framework executes the model "as is".
• Help developers understand the system’s architecture.
• Facilitate communication among team members.
• Aid in maintaining and evolving the software.

Class diagrams visually represent the structure of a system by showing classes, their attributes, methods, and relationships. They are fundamental tools in object-oriented design and play a crucial role in the software development lifecycle.
