Questions With Appropriate Solutions
Behavioral diagram Correct Answer - visualizes dynamic
behavior of software, such as the flow of an algorithm. Ex: A UML
activity diagram is a flowchart, used to describe the flow of an
activity or set of activities.
Analysis Correct Answer - Determines the goals for a program.
The program should support mean, median, mode, max and min
calculations.
Implementation Correct Answer - Builds the program
according to the design and writes the code. A programmer writes
each function using statements.
Design Correct Answer - Determines the specifics of how to
build the program. Each calculation will be a function. User types a
letter to invoke each calculation.
Testing Correct Answer - Checks that the program meets the
goals and checks that ea function works. Class diagrams are used in
this phase too and may help ensure that ea class from the diagram
exists in the program's code.
Object Correct Answer - a grouping of data (variables) and
operations that can be performed on that data (functions).
Abstraction Correct Answer - means to have a user interact
with an item at a high-level, with lower-level internal details hidden
from the user (aka information hiding or encapsulation)
, Structural diagram Correct Answer - visualizes static elements
of software, such as the types of variables and functions used in the
program.
Use case diagram Correct Answer - Behavioral diagram used to
visually model user interaction w/ a software program, actions
back/forth from the software & connections between diff.
components of the software. Used to specify behavioral req's of
programs.
Class diagram Correct Answer - structural diagram that can be
used to visually model the classes of a pc program, including data
members and functions; a code blueprint for creating an object that
is composed of data members and functions that operate on those
data members.
Sequence diagram Correct Answer - behavioral diagram that
shows interaction bet software components; indicates the order of
events; is commonly used to illustrate the order of events needed to
handle a particular scenario in software. Commonly created in
analysis or design phase.
In the Analysis phase Correct Answer - During this phase a use
case diagram is created to define how user interacts w/ software
In the Design phase Correct Answer - the use case diagram is
referenced to determine how the program is built. A class diagram is
commonly created in this phase and used as guidance in the
implementation phase.
In the testing phase Correct Answer - the use case diagram
may also be referenced such as when creating usability tests.
