CBS ISIS – Why? Reasons Migration from mainframe to client-server environment Almost 80% surveys fit to the Generic Statistical Business Process Model Heavy burden on IT staff to produce data processing SW All surveys processed in IT sector, controlled by IT staff Benefits General solution ready for majority of surveys Faster survey processing All survey business processes controlled by statisticians IT manpower spared for further development Page 4 ITDG 2009: Integrated Statistical Information System (ISIS) in Croatia

CBS ISIS – What? ISIS = Integrated Statistical Information System
Target of CBS ISIS is to manage a completely metadata-driven automated processing system through one general solution for: Data collection Data entry Data validation and cleaning processes Tabulation and dissemination processes Sampling and estimation Etc.

CBS ISIS – How? Components: Central metadata repository Data registers
Statistical warehouse Tools and applications Architecture: Data layer Business layer Presentation layer Page 6 ITDG 2009: Integrated Statistical Information System (ISIS) in Croatia

Metadata Model and Methodology
CROMETA: extension of Reference Model TM with additional concepts and/or characteristics Croatian Bureau of Statistics developed its own metadata model called CROMETA based on Reference ModelTM from the MetaNet project of Eurostat. It includes also some specific metadata from CBS and has nine groups or sections of metadata. Metadata objects in each section are closely related, but there are relationships between metadata from different sections.

Metadata Model and Methodology
CROMETA sections: Studies and questionnaires Variables and measurements Classifications Publications Organisational structure History and version handling General metadata Processing and validation rules Access and authorization rules Page 9 ITDG 2009: Integrated Statistical Information System (ISIS) in Croatia

CROMETA Model > 170 concepts > 230 tables Page 10

changed approach to data processing
Summary ISIS delivers a general solution for the majority of survey processing faster processing the majority of business processes controlled by statisticians changed approach to data processing changes in overall business culture in CBS Page 25 ITDG 2009: Integrated Statistical Information System (ISIS) in Croatia
