  1. The Domain Model

  2. Introduction • Partitions and illustrates the important domain concepts. • A classic object-oriented analysis activity. • What are the objects of interest in the this domain? • their attributes? • their relationships? • IMPORTANT: Not software objects, but a “visual dictionary” of domain concepts.

  3. A Domain Model Does Not Represent Software Objects • A model of domain concepts, not of software objects. • A “visual dictionary” of important words in the domain. • Uses UML static structure diagram notation.

  4. Terminology • UP domain model = book conceptual model

  5. Partitioning the Domain Model • Although this is conceptually accurate, a person will not actually draw package boxes around groups as in this example. Rather, a CASE tool will allow “drill down”.

  6. Finding Domain Concepts • Candidate lists • “Abbott” Analysis • Existing analysis patterns • Analysis Patterns, Fowler • Data Model Patterns, Hay • The Data Model Resource Book, Silverston

  7. Associations

  8. Multiplicity

  9. Focus on Important Associations

  10. Attributes • Show only “simple” relatively primitive types as attributes. • Connections to other concepts are to be represented as associations, not attributes.

  11. Do Not Use Attributes To Relate Concepts • Why not?

  12. An Example
