Documentation:Model

Definition

A model refers to an abstract representation of a system, process, or concept. It is a simplified and structured representation of a real-world entity, system, or phenomenon.

Models capture essential aspects, relationships, and behaviour without unnecessary details.

Models serve as a means of communication and understanding among stakeholders (developers, architects, users, etc.).

Purpose of Models

• Abstraction: Models abstract complex systems into manageable components.
• Analysis: They allow analysis, validation, and verification before actual implementation.
• Documentation: Models document design decisions, requirements, and system behaviour.
• Visualization: They provide visual representations for better comprehension.

Types of Models

1. Architectural Models: Describe the high-level structure and components of a system.
2. Behavioral Models: Illustrate how components interact and respond to events. Partially represented in MDriven with UML – State machines
3. Data Models: Represent data structures, relationships, and constraints. In MDriven, these are represented by the Class Diagram.
4. Process Models: Depict workflows, business processes, or system behaviour over time.

Examples of Models in MDriven

• UML diagrams (e.g., class diagrams, sequence diagrams).
• State diagrams for modeling system behaviour.
