    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.
