Domain Model Arrows

Domain model arrows. In enterprise architect a business domain model is represented as a conceptual class diagram as illustrated by this diagram from the car rental system model from the eaexample model. These often indicate the need for a generalization arrow. The model element at the tail of the arrow the client depends on the model element at the arrowhead the supplier.

The basic entity is a class. The arrow may be labeled with an optional stereotype and an optional name. It is a visual representation of the decomposition of a domain into individual conceptual classes or objects.

When translating a domain description into a class diagram look for the phrase is a or closely related terms. The domain model is created during object oriented analysis to decompose the domain into concepts or objects in the real world the model should identify the set of conceptual classes the domain model is iteratively completed it is the basis for the design of the software 4. The domain model as well as the use case diagram is created in the initial phase of software development.

A dependency is generally shown as a dashed arrow between two model elements. Domain modeling is one of the key design patterns approaches that assumes deriving the solution object model directly from the problem domain while preserving both behavior and data see 3. A domain model logically represents the business concepts to be fulfilled by the system and how they relate to one another.

A domain model is the most important oo artifact its development entails identifying a rich set of conceptual classes and is at the heart of object oriented analysis. Although they may look similar a domain diagram should use terms that are in the business domain. I assume i don t have to mention that our system will be programmed in the object oriented manners and therefore designed using the object oriented approach.

A video rental store. It should not be confused with a data diagram with represents the actual database design or architecture. It is a visual dictionary of noteworthy abstractions.
