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 ...
The UML representation of an association is a line connecting the two associated classes. At each end of the line there is optional notation. For example, we can indicate, using an arrowhead that the pointy end is visible from the arrow tail.
While in UML 1.x, activity diagrams were a specialized form of state diagram, [6] in UML 2.x, the activity diagrams were reformalized to be based on Petri net-like semantics, increasing the scope of situations that can be modeled using activity diagrams. [7] These changes cause many UML 1.x activity diagrams to be interpreted differently in UML ...
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 ...
In Unified Modeling Language (UML), a component diagram [1] depicts how components are wired together to form larger components or software systems. They are used to illustrate the structure of arbitrarily complex systems.
The Sequence diagram of UML Overview. In software engineering, a sequence diagram [1] shows process interactions arranged in time sequence. This diagram depicts the processes and objects involved and the sequence of messages exchanged as needed to carry out the functionality.
UML Diagrams used to represent the development view include the Package diagram and the Component diagram. [2] Physical view: The physical view (aka the deployment view) depicts the system from a system engineer's point of view. It is concerned with the topology of software components on the physical layer as well as the physical connections ...
A communication diagram [1] in Unified Modeling Language (UML) 2.5.1 is a simplified version of the UML 1.x collaboration diagram. [2]UML has four types of interaction diagrams:
