Logical Model Shows what the system must do, regardless of how it
will be implemented physically.
3 multiple choice options
Physical Model Describes how the system will be constructed during
the systems design phase.
3 multiple choice options
True or False True 1 multiple choice
option
While structured analysis
tools are used to
develop a logical
model for a new
information system, such
tools also can be used to
develop physical
models of an
information system.

Many systems
analysts create a
physical model of the
current system and
then develop a logical
model of the current
system before
tackling a logical
model of the new
system. Performing that
extra step allows them
to understand the
current system better.
Analysts develop each of the following:
1. physical model of the current system
Four-Model Approach 2. logical model of of the current system
3. logical model of the new system
4. physical model of the new system
True or False False 1 multiple choice
option
The major benefit of the
four-model
approach is that it
provides a clear picture
of new system
functions.

True or False False 1 multiple choice
option
The only advantage of
the four-model approach
is the added time and
cost
needed to develop a
logical and physical
model of the current
system.
A graphical description to describe an
Data Flow Diagram (DFD) information system using various symbols to
show how the system transforms data into
useful information.

A set of DFDs provides a
logical model that shows
what the system does,
not how it does it.
