A System Boundary in a Use Case Diagram represents the scope and limits of the system being modeled. It visually separates the internal elements of the system (Use Cases) from external elements (Actors).
With System Boundaries in Modeldraw's Use Case Diagram, you can:
Clearly define the scope of your system
Visually separate internal system functions from external entities
Organize Use Cases within a logical container
Illustrate subsystems or different components of a larger system
Enhance the readability of complex diagrams by grouping related Use Cases
Communicate the system's boundaries to stakeholders effectively
A System Boundary in Modeldraw's Use Case Diagram tool is typically represented by a rectangle that encloses the Use Cases. The System Boundary helps to clarify what is part of the system and what is external to it. Key points to understand about System Boundaries include:
The System Boundary explicitly shows what is included in the system and what is outside of it.
Use Cases are placed inside the System Boundary, while Actors remain outside.
The System Boundary can be named to identify the system or subsystem it represents.
You can have multiple System Boundaries in a single diagram to represent different subsystems or components.
While helpful, System Boundaries are not always necessary, especially in simple diagrams with few Use Cases.
