Question

True or false?

_____: Each class in a UML class diagram represents a class in an
object-oriented program.
_____: Relations in a domain model are typically represented as
attributes in a UML class diagram.
_____: Attributes are the preferred way of modelling relations in an
UML class diagram.
_____: Attributes in UML class diagrams are typically represented
as methods in object-oriented source code.
_____: Android software development is only possible in the Eclipse IDE.
_____: Each class in a UML class diagram is represented with a circle.
_____: An operation contract defines the pre- and post-conditions of a
step in a use-case scenario.
_____: Operation contracts are part of the design (they are not part
of the requirements).
_____: Operation contracts are not directly related to the domain model.
_____: Operation contracts must be expressed in first-order logic.
_____: UML packages can only be used in UML package diagrams.
_____: Simple names are globally unique.
_____: Name-spaces are typically organized in a tree-structure.
_____: Name-spaces allow one to reuse the same simple name for
different elements.
_____: The design class diagram is considered a static design model.
_____: In UML sequence diagrams, a method return value can be visualized
with an arrow, but the arrow is optional.
_____: The design class diagram is the most important element of a
software design because it includes all the information that is
contained in the dynamic design models.
_____: A box in a sequence diagram typically represents an object.
_____: A guard in a sequence diagram prevents the guarded method call
from occurring under any circumstances.
_____: Designing for visibility means that it is best to make methods
public.
_____: A box in a communication diagram represents the same amount of
items as the corresponding box in a domain model.
_____: A box in a communication diagram represents the same amount of
items as the corresponding box in a sequence diagram.
_____: An advantage of UML communication diagrams over UML sequence
diagrams is that they are more compact.
_____: Guards in communication diagrams have a different function
than guards in sequence diagrams.
_____: Operation contracts are part of the design (they are not part
of the requirements).
_____: The Apache Ant build management tool presented in class is rarely
used in Java development projects.
_____: The Rational Rose modeling tool presented in class is open source
software and freely available to all students of CSE 5324.
_____: Relations in a domain model are typically represented as
operations in a UML class diagram.
_____: Operations in a UML class diagram are typically represented as
methods in object-oriented source code.
_____: Multiplicity constraints are important in a domain model but they
cannot influence the resulting source code.
_____: Android software development is only possible in the Eclipse IDE.
