Study Notes
What is UML?
- UML stands for Unified Modeling Language
- It is a standardized modeling language used to create diagrams and models for software systems
- UML is used to visualize, design, and document software systems
Types of UML Diagrams
-
Structural Diagrams:
- Class Diagram: shows the relationships between classes and objects
- Object Diagram: shows the relationships between objects
- Component Diagram: shows the relationships between components
- Deployment Diagram: shows the deployment of components
-
Behavioral Diagrams:
- Use Case Diagram: shows the interactions between users and the system
- State Machine Diagram: shows the states and transitions of an object
- Activity Diagram: shows the flow of activities
- Sequence Diagram: shows the interactions between objects over time
- Communication Diagram: shows the interactions between objects
UML Notations
-
Classes and Objects:
- Class: represented by a rectangle with the class name and attributes
- Object: represented by a rectangle with the object name and attributes
-
Relationships:
- Inheritance: represented by an arrow
- Association: represented by a line
- Composition: represented by a diamond
