CBS ISIS: Architecture for Survey Processing Central Bureau of Statistics of Croatia MSIS 2009, Oslo, Norway, 18 -20 May 2009 Page *
Contents • ISIS – the idea behind • Live demo of ISIS tools • Future of ISIS Page *
CBS ISIS – What? • • Page * 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 – Why? • • Page * 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
CBS ISIS – How? • • Page * Components • Central metadata repository • Data registers • Statistical warehouse • Tools and applications Architecture • Data layer • Business layer • Presentation layer

Development of Metadata System • • Page * Central metadata repository = the core of the ISIS CROMETA model – based on Reference Model. TM (EUROSTAT - METANET project 2000 -2003): summary of concepts in different statistical metadata systems in a common model – CROMETA - extended reference model with necessary concepts or characteristics from other models (CROMETA Inventory, PC-Axis) – focus on operational metadata
OPERATIONAL METADATA STATISTICAL METADATA GENERAL METADATA Page *
Development of Survey Processor • • • Page * Metadata-driven tool for survey processing Consumer and producer of metadata Main statistical processes → module for each process – Monitoring – Definition of survey population – Survey design – Data import – Validation – Data cleaning – Tabulation
Development of Survey Processor Page *
Demo of Survey Processor Pilot survey Birth statistics (DEM-1) Page *
Future of ISIS • Further development of Survey Processor - new modules: • BI for management • automatic coding • manual coding • sampling etc. • Implementing metadata-driven dissemination of publications • Transfer of existing statistical data from mainframe • Integration of the CBS web site with CROMETA • ?
