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 usually starts by drawing use case diagrams. For agile development, a requirement model of many UML diagrams depicting use cases plus some textual descriptions, notes, or use case briefs would be very lightweight and just enough for small or easy project use. As good complements to use case texts, the visual diagram ...
UML diagrams used to represent the physical view include the deployment diagram. [2] Scenarios: The description of an architecture is illustrated using a small set of use cases, or scenarios, which become a fifth view. The scenarios describe sequences of interactions between objects and between processes.
Behaviour diagrams are used to illustrate the behavior of a system, they are used extensively to describe the functionality of software systems. Some Behaviour diagrams are: Activity diagram; State machine diagram; Use case diagram [note 4]
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.
Diagram illustrating how the relative emphasis of different disciplines changes over the course of the project. The unified process is an iterative and incremental development process. The elaboration, construction and transition phases are divided into a series of timeboxed iterations.
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 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 ...
