Automatic transition A transition triggered by the completion or termination of a state activity. Attribute A class member used to define a unit of information owned by the containing class, including such details as type and domain of values. Asynchronous event or action A type of message that does not require a response and does not require the sending object to wait. Assumptions Behaviors that must be handled by another use case prior to allowing anyone access to the use case in question. Association class Information about an association that has been abstracted into its own class.
#Unified modeling language example software
Artifact An artifact in the Unified Modeling Language (UML) is the specification of a physical piece of information that is used by a software development process or by deployment and operation of a system.Īssociation A relationship between classes that specifies the type of links that may be created between objects of the associated classes. It obtains the hardware addresses of hosts located on the same physical network. Can be used to describe any complex system, for example, "software architecture", or "network architecture" ARP Address Resolution Protocol is a part of the Internet layer. See also: Superclass Architecture Architecture refers to the way in which components fit together. See also: Composition Ancestor Any class that resides higher than the reference class in a generalization hierarchy. Usually used to model assemblies of objects to create new objects. See also: Composite Aggregation An asymmetric type association used to model a whole-part relationship between classes. Aggregate A class that represents the whole in a whole-part relationship. Agent An object that can be the source and destination of an interaction. Actor A person, system, or device that interacts with a system in a use case diagram. An activity is typically nonatomic, that is, it may be composed of any number of subtasks. Activity Processing that an object performs particular to a specific state.
In an object diagram, this is signified by making the object icon bold. In a sequence diagram, this is identified by widening the vertical timeline into a narrow rectangle. Active object An object in control of a thread or process that can initiate control activity. Activation The execution of an operation on an object or other call to an object to initiate a behavior on that object. Action state An object state that represents the execution of an action, typically the invocation of an operation. The intent of the representation is not a comprehensive description, but rather a description that is useful for a specific application or purpose.Īction A response to an event in a statechart diagram, typically part of the transition from one state to another and typically atomic (cannot be broken into subtasks). Abstraction A unique representation of a real-world entity. Abstract operation An operation signature without an associated implementation. Often used for items such as addresses, which contain a number of individual fields combined in a specific way and edited according specific rules unique to that combination. Abstract Data Type Abstract data type A class created to encapsulate a type of information common to an application.
UML offers a standard way to visualize a system's architectural blueprints, including elements such as: 1) activities, 2) actors, 3) business processes, 4) database schemata.Ībstract class A class that cannot be instantiated because a complete implementation has not been specified for all operations of the class. The Unified Modeling Language (UML) is used to specify, visualize, modify, construct and document the artifacts of an object-oriented software-intensive system under development.
UML includes a set of graphic notation techniques to create visual models of software-intensive systems. The standard is managed, and was created by, the Object Management Group. Unified Modeling Language (UML) is a standardized general-purpose modeling language in the field of software engineering.
