3 HCSO Statistical treats ADEL General Data Editing System Data recording, correction Raw data load GESA Survey Control System Blank questionnaires (XML/XSL) Maintenance Specification of the controls EDISC e-respondents XML Acknowledgement questionnaires with data pre-fill data of e- respondents via VPN Acknowledgement by MATÁV- AXELERO Blank questionnaires (HTML / JavaScript) via VPN webedi Personalised questionnaires Questionnaires filled in County offices paper questionnaires with data Personal contacts Client B a s i c features The questionnaires are defined in XML/XSL. All questionnaires are handled by the same XSL program. The specific elements of the questionaires are written in XML with respect to the forthcoming IQML standards. The electronic questionnaires are impersonalised by the data of the GESA system. It is part of the translation ( to HTML and Javascript ) happening within MATAV s e-commerce system. A client sees and handles a specific HTML form similar to the original paper questionaire. During data entry validation rules prevent the client to report syntactically and logically false data. The rules are limited to simple checks like numeric, obligatory, control sum, etc. Incoming data are converted to RDRMES format before the transmission to HCSO. RDRMES is received by EDISC, a message handling system. Output from EDISC is in questionaire specific format for the Oracle Loader. 3

4 B a s i c f e a tu r e s (continuation) Electronic responses loaded into the appropriate relational tables identical to those used with the the paper based ones. The tables belong to the Oracle data base of the ADEL application. Questionnaires filled-in fully, partly or left empty can be saved both on the client and the server side. Saved ( stored ) questionnaires can be (up-) loaded and continued. The authentication and data integrity can be guaranteed by electronic signature. The certification of the signature is delivered by MATÁV on active card basis. Data security is provided on the Internet by the standard HTTPS protocol, while the communication between the Internet provider (MATÁV) and the HCSO is established via a leased line and secured by using asymmetric keys. 4
