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 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 is a graphical language for visualizing, specifying, constructing, and documenting ...
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 ...
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.
The use of the terms parent and child is suggestive, but can be misleading. A is a type of B For example, "an oak is a type of tree", "an automobile is a type of vehicle" Generalization can only be shown on class diagrams and on use case diagrams.
Umple can be used to represent in a textual manner many UML modelling entities found in class diagrams and state diagrams. [2] Umple can generate code for these in various programming languages. Currently Umple fully supports Java, C++ and PHP as target programming languages and has functional, but somewhat incomplete support for Ruby.
