Study Notes
Entity Relationship Diagram
- A visual representation of the relationships between entities in a database.
- Uses symbols to represent entities, attributes, and relationships.
- Used for database design and development.
Domain Model Class Diagram
- A visual representation of the classes and relationships in a domain model.
- Shows the structure of a system from a business perspective.
- Used for software design and development.
Use Case Diagrams
- A visual representation of the interaction between users and a system.
- Shows the different use cases that users can perform.
- Used for requirements analysis and system design.
Entity Relationship Diagram
- Shows the relationship between entities and their attributes
- Used for database design
- Includes entities, relationships, and attributes
Domain Model Class Diagram
- Represents the concepts within a problem domain
- Shows classes, attributes, and methods
- Used for software design
Use Case Diagrams
- Represents the interactions between users and the system
- Shows actors, use cases, and relationships
- Helpful for understanding the system's functionality

Entity Relationship Diagram
- Diagrams that show the relationships between entities in a database
- Entities are represented by rectangles
- Relationships are represented by lines
- Relationships can be one-to-one, one-to-many, or many-to-many
Domain Model Class Diagram
- Diagrams that show the classes and relationships between them in a software system
- Classes are represented by rectangles
- Relationships are represented by lines
- Relationships can be association, aggregation, or composition
Use Case Diagrams
- Diagrams that show the interactions between users and a system
- Actors are represented by stick figures
- Use cases are represented by ovals
- Relationships between actors and use cases can be include, extend, or generalize
Entity Relationship Diagram
- A visual representation of the relationships between entities in a database.
- Depicts entities, their attributes, and the connections between them.
Domain Model Class Diagram
- Represents the structure of a system's data.
- Shows the classes of objects in the system and their relationships.
Use Case Diagrams
- Depict the interactions between users and a system.
- Show different actors (users) and the actions they can perform (use cases).
- Useful for understanding system functionality and requirements.
