Ø Both methods encourage the designer to show only the regular flows of information and not to be concerned with unique situations. Ø Both approaches require more than one “pass” through the diagramming or flowcharting process to accurately capture the essence of the system. The product of both methods is a model documenting the flow of information and/or documents in an information system.

Assignment#1
Solution
s
Week 2: Chapter 3
Chapter 3: Systems Documentation Techniques

2. 3.1 Identify the DFD elements in the following narrative:
A customer purchases a few items from a local grocery store.
Jill, a salesclerk, enters the transition in the cash register and
takes the customer’s money.
At closing, Jill gives both the cash and the register tape her
manager.(25 points)
Data Flows
: merchandise, payment, cash and register tape
Data Source
: customer
Processes
: capture sales and payment data and collect payment, give cash
and register tape to manager

3. Storage
: sales file (register tape), cash register
3.2 Do you agree with the following statement: “Any one of the
systems documentation procedures, such as DFD, can
adequately document a given system”? Explain. (25 points)
It is usually not sufficient to use just one documentation tool.
Every tool documents a uniquely important aspect of a given
information system. For example, system flowcharts are
employed to understand physical system activities including
inputs, outputs, and processing. In contrast, data flow diagrams
provide a graphic picture of the logical flow of data within an
organization.
Each alternative is appropriate for a given aspect of the system.
As a result, they work together to

4. fully document the nature and function of the information
system.
3.3 Compare the guidelines for preparing flowcharts and DFDs.
What general design principles and limitations are common to
both documentation techniques? (25 points)
Similar design concepts include the following:
Ø
Both methods require an initial understanding of the system
before actual documentation
begins. This insures that the system is properly represented by
the diagram.

5. Ø
Both measures require the designer to identify the elements of
the system and to identify the names and relations associated
with the elements.
Ø
Both methods encourage the designer to show only the regular
flows of information and not
to be concerned with unique situations.
Ø
Both approaches require more than one “pass” through the
diagramming or flowcharting
process to accurately capture the essence of the system.
The product of both methods is a model documenting the flow

6. of information and/or documents
in an information system. Both documentation methods are
limited by the nature of the models they employ, as well as by
the talents and abilities of the designer to represent reality.
3.4 Your classmates ask you to explain flowcharting
conventions using real-world examples. Draw each of the major
flowchart symbols from memory, placing them into one of four
categories:
input/output, processing, storage, and flow and miscellaneous.
For each symbol, suggest several uses.
(25 points)
Flowcharting symbols are divided into four categories:
1.
Input/Output Symbols

7. ·
Document:
an employee time card, a telephone bill, a budget report, a
parking ticket, a contract
·
Display:
student information monitors, ATM monitors, the monitor on
your microcomputer.
2.
Processing Symbols

8. ·
Processing:
processing a student payroll program, assessing late fees
·
Manual operation:
writing a parking ticket, preparing a paper report, collecting
and entering student payments
3.
Storage Symbols

9. ·
Magnetic disk:
alumni information data base, a report stored on your PC hard
disk
·
Magnetic tape:
archival student information
4.
Flow
(Miscellaneous)
·

10. Terminal:
A beginning, end, or point of interruption in a process or
program; also used to indicate an external party.
·
Communication link:
a telephone linkage that connects you to an on-line data base.
