The information from the computerized system. 2. It

The
input design is the link between the information system and the user. It
comprises the developing specification and procedures for data preparation and
those steps are necessary to put transaction data in to a usable form for
processing can be achieved by inspecting the computer to read data from a
written or printed document or it can occur by having people keying the data
directly into the system. The design of input focuses on controlling the amount
of input required, controlling the errors, avoiding delay, avoiding extra steps
and keeping the process simple. The input is designed in such a way so that it
provides security and ease of use with retaining the privacy. Input Design
considered the following things:

Ø What
data should be given as input?

Ø  How the data should be
arranged or coded?

Ø  The dialog to guide the
operating personnel in providing input.

Ø Methods
for preparing input validations and steps to follow when error occur.

 

OBJECTIVES

 

1. Input Design is
the process of converting a user-oriented description of the input into a
computer-based system. This design is important to avoid errors in the data
input process and show the correct direction to the management for getting
correct information from the computerized system.

 

2. It is achieved by
creating user-friendly screens for the data entry to handle large volume of
data. The goal of designing input is to make data entry easier and to be free
from errors. The data entry screen is designed in such a way that all the data
manipulates can be performed. It also provides record viewing facilities.

3. When the data is
entered it will check for its validity. Data can be entered with the help of
screens. Appropriate messages are provided as when needed so that the user  will not be in maize of instant. Thus the
objective of input design is to create an input layout that is easy to follow
