Sep 10, 2021 · Use Case Diagram Guidelines. Although use case diagrams can be used for various purposes there are some common guidelines you need to follow when drawing use cases.. These include naming standards, directions of arrows, the placing of use cases, usage of system boxes and also proper usage of relationships. An interaction diagram is either a sequence diagram or a communication diagram, both of which show essentially the same information. These diagrams, along with class diagrams, are used in a use case realization, which is a way to achieve or accomplish a use case. Instead, they tend to choose which UML diagram types are the most meaningful that help the team and other stakeholders better understand the software. For example, a team that works on UIs might find Use Case diagrams helpful, while the back-end team might find Sequence and State-machine diagrams work better for their software. Sequence Diagram: i) SD shows the interactions between objects in the sequential order. ii) During the requirements phase of a project, analysts can take use cases to the next level by providing a more formal level of refinement. When that occurs, use cases are often refined into one or more sequence diagrams.

A use case diagram is a graphical depiction of a user's possible interactions with a system.
