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

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

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)
