In a use case diagram, the system boundary is a boundary surrounding the use cases which indicates the system. Resize a System Boundary shape Select the shape, and then drag a selection handle. Rename a System Boundary shape Select the shape, and then type the name you want. ...
The system boundary box must be the first element placed in a use-case diagram. It distinguishes the border between use cases and actors (use cases are inside the borders of the system boundary box and actors are outside of it). Procedure Click the Boundary box button . Click once in the...

Fig. 2. Flow diagram for challenges and opportunities associated in the IoT of agriculture. The complexity of IoT was investigated in a report by Madakkam et al. [17]. The equipment, middleware, and IoT software description can have a negative effect on farming. Patil et al. [18] took ...
You can also define a Use Case as the classifier of a System Boundary element, to link the elements enclosed in the System Boundary (such as parts of an Activity diagram) to their representation in a logical Use Case. See http://www.sparxsystems.com.au/resources/map_uc.html....

Packages can also be used to group classes, collaborations, subsystems or a complete view of the system such as a use case model. We can also use packages to nest models; we might have a high-level class diagram that contains a package which itself contains a class diagram, and so on....
A“boundary” is basically the line between two nodes on an architecture diagram. It might be physical, logical, cross-machine, cross-network, cross-boundary, or just inter-component. The Measures When looking at each boundary I consider 4 measures; ...
