biggest banks, i.e. Hansabank, SEB Eesti Ühispank or Sampo Bank).

Response rate

•eSTAT average 9%, highest 100%, some questionnaires 30-50% (smaller samples);•File import average 15%, some questionnaires 50% (Intrastat).


Technical information

•Application Server: Linux server, BEA Web logic 8.2SP5; •DBMS: Oracle Database 10g; •Questionnaire designer: client-server program in Java; •Questionnaire presentation: Java Server Page files, checking rules in xslt files.•Authentication: Java standard jaas components.
