UML Use Case Diagram Example. Social Networking Sites Project

In the early stages of a development project, use case diagrams are used to describe real-world activities and motivations. A use case diagram (use case: In a use case diagram, a representation of a set of events that occurs when an actor uses a system to complete a process. Normally, a use case is a relatively large process, not an individual step or transaction.) is a dynamic or behavior diagram in UML.

Use case diagrams are valuable for visualizing the functional requirements of a system that will translate into design choices and development priorities. You can refine the diagrams in later stages to reflect user interface and design details.

They also help identify any internal or external factors that may influence the system and should be taken into consideration.

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
