A use case diagram [1] is a graphical depiction of a user's possible interactions with a system. A use case diagram shows various use cases and different types of users the system has and will often be accompanied by other types of diagrams as well. The use cases are represented by either circles or ellipses. The actors are often shown as stick ...
Use case analysis is a technique used to identify the requirements of a system (normally associated with software/process design) and the information used to both define processes used and classes (which are a collection of actors and processes) which will be used both in the use case diagram and the overall use case in the development or redesign of a software system or program.
In software and systems engineering, a use case is a potential scenario in which a system receives an external request (such as user input) and responds to it. A use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language (UML) as an actor) and a system to achieve a goal.
Use case diagrams are used to identify the actor (users or other systems) and the processes they perform. System sequence diagram: A system sequence diagram (SSD) is a picture that shows, for a particular scenario of a use case, the events that external actors generate, their order, and possible inter-system events.
Use-case modelling to describe system environments, user scenarios, and test cases. UML has support for object-oriented system specification, design and modelling. Growing interest in UML from the embedded systems and realtime community. Support for state-machine semantics which can be used for modelling and synthesis.
The sense of artifacts as byproducts is similar to the use of the term artifact in science to refer to something that arises from the process in hand rather than the issue itself, i.e., a result of interest that stems from the means rather than the end. To collect, organize and manage artifacts, a software development folder may be utilized.
Use Case diagrams represent a set of Use Cases, which are textual descriptions of how an actor achieves the goal of a use case. for Example Customer Places Order. ArchiMate : ArchiMate is an open and independent enterprise architecture modeling language to support the description, analysis and visualization of architecture within and across ...
Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
