3. Page 3 CBS ISIS: Architecture for Survey Processing 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.

4. Page 4 CBS ISIS: Architecture for Survey Processing 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
