Using Mainframe:

(NEC ACOS 500 in 1980)

(NEC ACOS 1520 in 1990)

Batch Processing (not interactive)

1. Decentralized & Distributed Data Processing:

Encourage End-users Computing: subject matter units are

entitled to process their own survey under coordination ofdata processing division.

Develop application in-house by HQ & decentralize operationto Regional offices.

Implement Distributed / Client-Server Data Processing

Model.2. ITDepartment (Directorate of SIS) focuses on IT

infrastructures & complex DP Systems such as Censuses.

PC based Client-Server Data

Processing

Using Scanner: Kodak DS3500

Speed: 3500 forms / hour

Use of OMR, ICR: Nestor

Reader

ICR Ascent-Capture: started in

2003 (Census of Agriculture).

Data Processing Support forPopulation Census 2000


10/21

PC 2000 Data Capture Stages

Scan documents (produce image file)

Recognize image

(produce ascii characters)

Verification & Correction (operators decidecharacters ambiguous to recognize engine)

Completion completeness check

Release save into database


11/21

Experience from PC 2000 Unexpected low quality of enumerators handwriting torecognize by ICR Unable to recognize characters correctly

Rejected too many values (too high confidencelevel)

Accepted incorrect values (too low confidencelevel) realized from tabulation output

Should check-digit help to increase accuracy ? Ineffective learning engine

In a LAN environment using MS-SQl Server, 4concurrent scanning processes slow down the whole DPactivities consisting of 3 recognize stations, 10correction stations,and 25 computer editing stations.


12/21

Experience from PC 2000

Extra work to erase & rewrite Census Form Powder from rubber eraser stick on Census

forms & affected Scanner performance

Costly maintenance effort of Scannerswhich spread over all provinces Relatively high cost (investment) for Data

Capture H/W& S/W

However, Data Capture using scanner wasable to shorten Data Processing CompletionTime.

It was not easy to find out well motivatedenumerators & Data Capture operators.


13/21

PC2010 Data Processing Plan

Main Documents: Short Form : L for Listing & basis for 10%

sample, using data entry (DE),: C using scanner, complete

enumeration (100%) of households

& members

Long Form : S using data entry / scanner,10% sample.

Estimation:

No of Districts / Regency = 456

No of Sub-districts = 5,901

No of villages = 72,084

No of Census Blocks = 658,308 (in year 2000)

No of smallest Administrative Areas (SLS) = 900,000

No of households = 64 million

No of population = 236 million

PC2010 Data Processing Plan (cont)

Issues on existing Scanners:

Kodak DS3500 procured for PC 2000: 79 units

About 60 % of them need spare-parts replacement

Spare-parts are discontinued. (Dicom Singaporeeager to reserve all available spare-parts to BPS)

Running out of Ascent Capture Counter (dongle) limit

Operable uncertainty for PC 2010


17/21

1. Utilize scanners with character recognitiontechnology (OMR, OCR, ICR), focused on OMR.

2. Expect ICR with better Learning Engine capability.

3. Procurement of Scanning H/W and S/W in 2009.

4. Formation of 8 Data Processing Centers.

5. Utilize SMS facility for transmitting and accessingdata, as well as monitoring data collection activities.

6. Utilize web-based application for monitoring dataprocessing activities.

7. In 2008, all of 33 province level offices and some(34) district / city level offices are connected usingVirtual Private Network (VPN).
