📚 3. THEORY & CONCEPTS
3.1 What is a Use Case Diagram?
A Use Case Diagram is a behavioral UML diagram that represents the functional requirements of a system by showing the interaction between users (actors) and the system's use cases. It provides a high-level view of the system's functionality from the user's perspective using standardized graphical notation with enhanced visual elements for better understanding.
3.2 Enhanced Components Analysis
| Component | Enhanced Visual Symbol | Description & Purpose | Color Coding |
|---|---|---|---|
| Primary Actor | Enhanced Stick Figure with Icons | External entity (user, system, or device) that initiates interaction | Dark Blue (#2c3e50) |
| Use Case | Gradient-filled Oval with Shadow | Specific functionality or service provided by the system | Orange Gradient (#fff8e1 to #ffecb3) |
| System Boundary | Rounded Rectangle with Gradient | Defines the scope and boundaries of the system under development | Blue Gradient (#667eea to #764ba2) |
| Association | Curved Line with Directional Arrow | Communication path between actor and use case with better visual flow | Color-coded by Actor Type |
| Include Relationship | Curved Dashed Arrow with «include» | Base use case mandatorily includes behavior from another use case | Red (#e74c3c) |
| Extend Relationship | Curved Dashed Arrow with «extend» | Optional behavior that can extend the base use case under conditions | Red (#e74c3c) |
