UML is a graphical language for visualizing, specifying, constructing, and documenting information about software-intensive systems. [3] UML gives a standard way to write a system model, covering conceptual ideas. [4] [note 2] With an understanding of modeling, the use and application of UML can make the software development process more efficient.
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 ...
It is used for general conceptual modeling of the structure of the application, and for detailed modeling, translating the models into programming code. Class diagrams can also be used for data modeling. [2] The classes in a class diagram represent both the main elements, interactions in the application, and the classes to be programmed.
Initially, when n=2, and f(n-2) = 0, and f(n-1) = 1, then f(n) = 0 + 1 = 1. Consider one possible way of modeling production of the Fibonacci sequence.. In the first UML object diagram on the right, the instance in the leftmost instance specification is named v1, has IndependentVariable as its classifier, plays the NMinus2 role within the FibonacciSystem, and has a slot for the val attribute ...
Diagramming in this context means creating and editing UML diagrams; that is diagrams that follow the graphical notation of the Unified Modeling Language. The use of UML diagrams as a means to draw diagrams of – mostly – object-oriented software is generally agreed upon by software developers. When developers draw diagrams of object ...
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.
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 ...
Important milestones in the evolution of the UML: One of the most significant object modeling languages currently in use. [1] It is common to equate the modeling language and the modeling methodology. For example, the Booch method may refer to Grady Booch's standard for diagramming, his methodology, or both.
