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 ...
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 representations of use cases are also effective facilitating tools for ...
UML (Unified Modeling Language) is a modeling language used by software developers. [1] UML can be used to develop diagrams and provide users (programmers) with ready-to-use, expressive modeling examples. [note 1] Some UML tools generate program language code from UML. [2] UML can be used for modeling a system independent of a platform language.
UML logo. The unified modeling language (UML) is a general-purpose visual modeling language that is intended to provide a standard way to visualize the design of a system. [1] UML provides a standard notation for many types of diagrams which can be roughly divided into three main groups: behavior diagrams, interaction diagrams, and structure ...
UML use case diagram with two actors (Parent-Teacher and Child) and 5 use cases. An actor [1] in the Unified Modeling Language (UML) "specifies a role played by a user or any other system that interacts with the subject." [1]
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.
Use case diagram; ... For example, Figure 1 shows a UML state diagram corresponding to the computer keyboard state machine. ... it is the case that when UML state ...
These tasks may include repetitive, simple, or complex tasks. The purpose is to illustrate the use case in a visual format. Familiarity with unified modeling language (UML) is needed to construct a system sequence diagram. These models show the logic behind the actors (people who affect the system) and the system in performing the task.
