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).

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

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.

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.

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

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).
