Domain Model: Class Diagrams Flashcards

Study Notes

Class and Class Diagrams

Class: A group of objects sharing common state and behavior.
Class Diagram: Visual representation outlining types of entities in a system and their structural relationships.

Conceptual Objects

Conceptual Object: A distinct set of instances representing a domain-specific concept, managed by the system.
Types of Conceptual Objects: Include Entity, Association, Event, and Agent.

Types of Conceptual Objects Explained

Entity: Represents a passive and autonomous object within the system.
Association: Symbolizes a connection or link between dependent objects.
Event: An instantaneous object in the context of the system.
Agent: An active and autonomous object that performs actions.

Relationships and Structures

Association Relationship: Defined by multiplicity, indicating the potential count of participating objects in the association.
Aggregation: Describes a whole-part relationship, indicating a collection of objects.
Composition: Represents ownership, where the lifetime of contained objects is tied to the lifetime of the container object.
Generalization: A concept that abstracts common features from multiple entities into a general class.

Steps to Develop Class Diagrams

Step 1: Identify core classes that will be included in the model.
Step 2: Construct class structures that define associations between these classes.
Step 3: Define attributes associated with each class to detail their properties.
Step 4: Specify messages that can be communicated between classes to outline interactions.
Step 5: Refine the class model to enhance clarity and accuracy in representing the system.
