Study Notes

Domain Driven Design

Domain Driven Design focuses on solving organizational problems through code, prioritizing resources on the business logic of an application.
The domain refers to the world of the business, including rules, processes, and existing systems.

Domain Model

A domain model is a structured visual representation of interconnected concepts or real-world objects.
It incorporates vocabulary, key concepts, behavior, and relationships of all entities within the domain.
The domain model should be accessible and understandable by everyone involved in the project.
A domain model can be represented through diagrams, code examples, or written documentation.
Class diagrams are commonly used to illustrate domain models, showing:
- Domain objects or conceptual classes
- Associations between conceptual classes
- Attributes of conceptual classes

The Model

The model represents the solution to the problem, often simplifying the bigger picture to focus on important aspects.
The model and domain model shape each other.
The domain model is the backbone of the language used by all team members.
The domain model is distilled knowledge.

General Steps in Domain Modelling

Prepare a problem statement for the system being developed.
Identify classes and objects.
Develop a data dictionary.
Identify associations between classes.
Identify attributes of classes and association classes.
Structure objects using inheritance.
Verify access paths for likely queries.
Iterate and refine the model.
