Authentication and confidentiality in eSTAT (5) • Public Key Infrastructure for data encryption; • Data managers have direct access to data; • Raw data transmission to validation and aggregation databases.
Data integrity • Integrity problems at the beginning of implementation and during continuous development; • Backups of the database; • Recovery Manager and roll-back.
Availability • Availability problems due to different infrastructure problems and a continuous development of new modules; • Number of parallel online user about 50-200, it has not caused any overload of the system yet.
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. JAAS is J2SE integrated (since version v1.4) authentication and authorization component (API). JAAS includes also Java VM Pluggable and Stackable architecture for configuration of the modules; • iPizza protocol.
The best innovation in Estonian public administration in 2006 • eSTAT was declared the best innovation in Estonian public administration in 2006 in September 2006 by the Secretary of State.
