Use Case Diagram Example - Actor, Entity, and Process Relationships #305639 (License: Personal Use)

This diagram demonstrates foundational UML use case modeling components: a human actor, a document symbolizing a system or data artifact, an oval representing an entity (e.g., database or external system), and a rounded rectangle for a simplified process. Arrows indicate extended/included relationships and generalization, clarifying how behaviors interact and inherit.

Used in software engineering documentation, requirements analysis, and academic teaching to explain UML use case notation; targets developers, analysts, and students seeking visual guidance on system behavior modeling.
