[U]
-
- Unified Modeling Language [
UML98].
In the Rational Unified Process Glossary, definitions from the Unified
Modeling Language are indicated by the symbol:
- uninterpreted
-
- A placeholder for a type or types whose implementation is not specified by
the UML. Every uninterpreted value has a corresponding string
representation. See: any [CORBA].
- usage
-
- A dependency in which one element (the client)
requires the presence of another element (the supplier)
for its correct functioning or implementation.
- use case (class)
- A use case defines a set of use-case
instances, where each instance is a sequence of actions a system
performs that yields an observable result of value to a particular actor. A
use-case class contains all main, alternate flows of events related to
producing the 'observable result of value'. Technically, a use-case is a
class whose instances are scenarios.
-
- The specification of a sequence of actions, including variants, that a
system (or other entity) can perform, interacting with actors
of the system. See: use-case
instances.
- use-case diagram
-
- A diagram that shows the relationships among actors
and use cases within a system.
- use-case instance
- A sequence of actions performed by a system that yields an observable
result of value to a particular actor.
-
- The performance of a sequence of actions being specified in a use
case. An instance of a use case. See: use-case
class.
- use-case model
-
- A model that describes a system’s functional requirements
in terms of use cases.
- use-case package
- A use-case package is a collection of use cases, actors, relationships,
diagrams, and other packages; it is used to structure the use-case model by
dividing it into smaller parts.
- use-case realization
- A use-case realization describes how a particular use case is realized
within the design model, in terms of
collaborating objects.
- use-case view
- An architectural view that
describes how critical use cases are performed in the system, focusing
mostly on architecturally significant components (objects, tasks, nodes). In
the Unified Process, it is a view of the use-case
model.
- utility
-
- A stereotype that groups global variables and procedures in the form of a
class declaration. The utility attributes and operations become global
variables and global procedures, respectively. A utility is not a
fundamental modeling construct, but a programming convenience.
[V]
- version
A variant of some artifact; later versions of an artifact typically expand
on earlier versions.
view
A simplified description (an abstraction) of a model, which is seen from a
given perspective or vantage point and omits entities that are not relevant to
this perspective. See also architectural view.
A projection of a model, which is seen from a given perspective or vantage
point and omits entities that are not relevant to this perspective.
view element
A view element is a textual and/or graphical projection of a collection of model
elements.
view projection
A projection of model elements onto view
elements. A view projection provides a location and a style for each
view element.
visibility
An enumeration whose value (public, protected, or private) denotes how the model
element to which it refers may be seen outside its enclosing namespace.
vision
The user's or customer's view of the product
to be developed, specified at the level of key stakeholder
needs and features of the system.
value
An element of a type domain.
vertex
A source or a target for a transition in a state machine. A vertex can be
either a state or a pseudo-state. See: state,
pseudo-state.
[W ]
- work guideline
A description which provides practical guidance on how to perform an
activity or set of activities. It usually considers techniques which are
useful during the activity.
worker
A definition of the behavior and responsibilities of an individual, or a set
of individuals working together as a team, within the context of a software
engineering organization. The worker represents a role
played by individuals on a project, and defines how they carry out work.
workflow
The sequence of activities performed in a business that produces a result of
observable value to an individual actor of the business.
workflow detail
A grouping of activities which are performed in close collaboration to
accomplish some result. The activities are typically performed either in
parallel or iteratively, with the output from one activity serving as the
input to another activity. Workflow details are used to group activities to
provide a higher level of abstraction and to improve the comprehensibility of
workflows.
