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 ...
The main specification notations in UML-RSDS are UML class diagrams and use cases, together with Object Constraint Language (OCL) expressions, used to define invariants and operation pre and post-conditions. [5] Either a graphical or textual notation can be used for UML-RSDS specifications. For example, a simple class specification could be ...
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 (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.

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.
Static modeling - use of class diagrams to describe structure; Static operation - an operation that does not relate to a specific object but is at class level; Stereotype - a notation allowing the extension of UML symbols. Some are defined within Profiles. Examples of predefined UML stereotypes are Actor, Exception, Powertype and Utility ...
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.
