2. Design is the process of developing specification
for a candidate system that meet the criteria
established in system analysis.
3. 1.INPUT DESIGN
It is the process of converting user oriented inputs
to a computer based format.
CLASSIFICATION OF INPUT DESIGN
A)Input data
The goal of designing input data is to make data
entry as easy, logical, and free from errors as
possible.
4. •Contd
In entering date, operators need to know the
following:
1.The allocated space for each field.
2.Field sequence , which must match that in the
source document.
3.The format in which data field are entered :
For example, filing out the data field is
required through the edited format mm/dd/yy .
5. Source document
A source document should be logical and easy to
understand. Each area in the form should be clearly
identified.
For example a field as simple as date of birth may be
written in four different ways:
1.19 September 1935
2.Sept. 19,1935
3.9/19/35
4.19/9/35
6. Source data are input into the system in a variety
of ways:
•Punch cards
•Key-to-diskette
•MICR
•Mark-sensing readers
•Optical character recognition
•Optical bar code readers
7. 1.Computer output is the most important and direct source
of information to the user.
2.Efficient ,intelligible output design should improve the
system ‘s relationship with the user and help in decision
making.
The following media devices for computer output:
1.Micr readers
2.Line ,matrix and daisy wheel printers
3.Computer output microfilm(COM)
4.CRT screen display
8. The standards for printed output suggest the
following
• Give each output a specific name or title
• Provide a sample of the output layout, including areas
where printing may appear and the location of each
field.
• State whether each output field is to include significant
zero ,spaces between fields, and alphabetic or an other
data
• Specify the procedure for proving the accuracy of
output data
9. WHAT IS A FORM?
Form is a business document that contain some
predefined data and may include some area
where additional data is to be filled.
It is a tool that carries data and information.
10. 1. Flat form
A flat form is single copy form prepared manually or
by machine and printed on any grade of paper.
It is the easiest form of design , print, and reproduce
It has the low volume used , and
It is least expensive
16. Scheduled: produced at predefined time intervals for routine
information needs
Key-indicator: provides summary of critical information on
regular basis
Exception: highlights data outside of normal operating ranges
Drill-down: provides details behind summary of key-indicator
or exception reports
Ad-hoc: responds to unplanned requests for non-routine
information needs
19. RULES AND CAPTION
In designing form ,use rules(lines) to guide the human eye to
read and write data groups.
It specifies what information to write in the space provided.
Rules can used to make boxes in which the user placed data.
Caption tells the user what information goes in the particular
position.
20. BOX DESIGN
While designing a form its easy to form box style rule , with
captions in the upper left corner.
Forming box design reduces the form size by 25 to 40 percent.
SPACING REQUIREMENT
Spacing requirement basically tells the space should be provided
according to the information the form asked.
21. BALLOT BOX AND CHECK-OFF DESIGN
Using ballot or check-off questions that can be
answered or no can generally reduce the amount of
required writing.
The user preference simply by checking off the desired
box.
22. A well designed form with clearly stated caption should be self
instructing.
A sample of the instruction as follows:
Date: fill in the current date
Name: print the legal name in full
Description: give title of each part
Signature: your supervisor must sign here
23. Forms may be printed on paper of different colors, grades, and
weight.
Paper weight is based on a ream of 500 sheets that are 17 by
22 inches
Three major factors to consider in paper selection:
1.The number of times the form will be handled .
2.The count of folding it will receive,
3.The extent of exposure to the environment.
24. It basically tells that how much cost should
incurred while making a actual form or printed
form.
The cost like:
•Ink
•Machine
•Labor
•Paper
