1 Corporate Data Model (CDM) Underlying principle:4 datastores 1.INPUT-raw data 2.CLEAN UNIT-cleaned data 3.AGGREGATE-aggregated data 4.DISSIMINATION-published data  CDM was seen as ≈ active DWH

2 Corporate Data Model (CDM) Main characteristics: All (statistical) processes must use the 4 datastores Processing systems interact on the data stores At some moments: snap shots, which build next data store It is possible to work further on the same (snap shotted) data store Simultanious updating of / on data is mainly organisational issue

3 Corporate Data Model CSO - Ireland INPUT CLEANED DATASETS AGGREGATE DATASETS DISSEMINATION DATA MANAGEMENT STORE ADMINISTRATIVE DATA CENTRE 2OPERATIONAL IMPLEMENTATIONS Surveys Admin data

4 Data Management Store (DMS) First implementation of CDM Mainly survey data Data tables are created and populated through the DMS applications. Metadata must be entered as the data tables are created. Metadata capturing = minimal  bottleneck BR outside DMS (stand alone)

6 Administrative Data Centre (ADC) Developed for organisational reasons Only Admin data A catalyst to exploit administrative data for statistical purposes Interface with public authorities on admin data flows to CSO Clearing house inside CSO for admin data Data governance with respect to admin data

7 Administrative Data Centre (ADC) Has analysis layer R&D on available data To develop new datasets Without specific needs / demands from statistics
