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.
In summary, models are essential tools in software development, allowing us to reason about, communicate, and design complex systems effectively.
