Q

_____ shows the distance between two time instants for a message invocation.

A

Duration message

17
Q

Alternative multiple fragments: only the one whose condition is true will execute.

A

alt

18
Q

Optional: the fragment executes only if the supplied condition is true. Equivalent to an alt only with one trace.

A

opt

19
Q

Parallel: each fragment is run in parallel.

A

par

20
Q

Loop: the fragment may execute multiple times, and the guard indicates the
basis of iteration.

A

loop

21
Q

Critical region: the fragment can have only one thread executing it at once.

A

region

22
Q

Negative: the fragment shows an invalid interaction.

A

neg

23
Q

Reference: refers to an interaction defined on another diagram. The frame is drawn to cover the lifelines involved in the interaction. You can define parameters and a return value.

A

ref

24
Q

Sequence diagram: used to surround an entire sequence diagram.

A

sd

25
Q

_____ is a static diagram. It represents the static view of an application. _____ is not only used for visualizing, describing, and documenting different aspects of a system but also for constructing executable code of the software application.

A

Class diagram

26
Q

The class shape itself consists of a rectangle with three rows:

A

top row = name of the class
middle row = attributes of the class
bottom row = methods (operations) of the class

27
Q
  • Represents an “is-a” relationship.
  • An abstract class name is shown in italics.
  • SubClass1 and SubClass2 are specializations of Super Class.
  • A solid line with a hollow arrowhead that point from the child to the parent class
A

Inheritance

28
Q
  • A structural link between two peer classes.
  • There is an association between Class1 and Class2
  • A solid line connecting two classes
A

Simple Association

29
Q
  • Class2 is part of Class1.
  • Many instances (denoted by the *) of Class2 can be associated with Class1.
  • Objects of Class1 and Class2 have separate lifetimes.
  • A solid line with an unfilled diamond at the association end connected to the class of composite
A

Aggregation

30
Q
  • Objects of Class2 live and die with Class1.
  • Class2 cannot stand by itself.
  • A solid line with a filled diamond at the association connected to the class of composite
A

Composition

31
Q
  • Exists between two classes if the changes to the definition of one may cause changes to the other (but not the other way around).
  • Class1 depends on Class2
  • A dashed line with an open arrow
A

Dependency

32
Q

four types of visibility:
