Data processing – web-based input

- on line, government use only network because of security reasons

Web-Based Data Input Method


After we connect the Census web site, surveycompleted data are input and sent to the KNSO ’

DB by personal computer in the field.


- We need a new input process paradigm, different from OMR, ICR, for processing large scaled data as census quickly.

- Data processing method by OMR needs much time, when we make out questionnaires.

- In Korea, high developed IT basement can construct high speed national administration network and spread personal computer per 1 person to all executive agency.

- We can meet user ’ s demand by offering survey ’ s result quickly for the

‘ timeliness ’ .


- Preview

(1) Construct web site

(2) Develop input program

(3) Load of server and network

(4) Security module & exclusive network

(5) Surplus band width of network

(6) Input place

(7) Prepare equipment

- Data input

(1) Educate how to input data

(2) Input and modify questionnaires ’ data

- Editing

(1) First editing

(2) Second editing

(2) X-internet method is developed for input program, which has merits between web and C/S.

(1) Screen component and input method are designed simple for users.

(2) At input place, we prepare management staffs focused exclusively on PC and network.

- Web-based data processing method can shorten input period, but the number of input person is increased.

As a result, usual vitality in former days is disappearing in rural communities.

Exposure to world competition system is inevitable and accelerated as time goes by.
