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.
