Definition of a Model

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

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

Model Driven Architecture and Model-Driven Development

Read more here about different software development strategies using models: BestPractices:Model Driven

Examples of Models in MDriven

UML (Unified Modeling Language) diagrams (e.g., class diagrams, sequence diagrams).
State diagrams for modeling system behaviour.

-==== Model-Driven Development (MDD) ====
-MDD emphasizes creating software directly from models.
-Models serve as the primary artifacts, and code is generated automatically.
-MDD improves productivity, consistency, and maintainability.
