The ESS VIP "Data Warehouses"

Slide 2
Scope and objectives
Overall scope and objectives: •Analysis, design and implementation of ESS data warehouses to support the business requirements of the ESS VIPs (in particular on transport and price statistics) and redesigned ESS business processes in general;•The cross-cutting project covers ESS data warehouses for production and reference/dissemination; •It follows the service-oriented architecture of the ESS VIPs which will lead to more business process integration in the ESS;
Slide 3
Relation with ESS VIP projects
The cross-cutting ESS VIP "data warehouses" is closely related to the ESS VIP "Data warehouses in price and transport statistics". There will be a mutual impact between the cross-cutting project and the specific business cases in those two statistical domains.I.e.: the data warehouse work done in both statistical domains will provide an input to the general business case of the cross-cutting project "Data warehouses" and its implementation.The outcome of the ESS data warehouses project should also be usable also for those two domains.
Slide 4
Link with previous projects
Input from previous projects: •From the VIP "Enhanced Dissemination Chain" (dealing with improvements of the current Eurostat dissemination, also with some impact on Member states); •In Transport statistics: experiences made with using data sources from other organisations and generation of modal split indicators; •Input from ESSnets such as the ESSnet on data warehouses (see the subsequent presentation).
The ESS VIP "Data warehouses" is a cross-cutting VIP using ESS technical, statistical and IT standards. This VIP is related to all
specific VIPs (such as SIMSTAT, NAPS, etc.).

Slide 7
What parts of the ESS "To-be-state" are concerned by the ESS VIP Data Warehouses?
The following parts are concerned:
• European Statistics – dissemination• European statistics – production processes• Shared services • Common ESS standards & models
Primary data collection is not in the focus of this cross-cutting ESS VIP.

Production data versus reference data
Production data Reference data
Accessible to public No Yes
Accessible within ESS authorities
Yes Yes
Sharing at collection/production level
Yes Yes (in the sense that the production of statistics needs to
make use of reference data)
Sharing at reference/
dissemination level
No Yes
Include confidential data
Yes No
Slide 11
Expected benefits for Member states
• Improvement of the quality of European statistics through more integrated statistical business processes;
• Broader use of statistical and technical ESS standards in more integrated ESS data warehouses;
• More cross-domain statistical production and dissemination;• Improvement of national/international data/metadata
exchange processes;• More integrated dissemination of European statistics;
Over time: reduction of production and dissemination costs for European statistics.
Slide 12
Next steps
As requested by the ESSC meeting in 11/2012, the business case for the ESS cross-cutting project "Data Warehouses" needs to be further elaborated.This needs to be done in taking into consideration the input from related ESSnets, the work done in transport and price statistics and in other related projects. This more elaborated business case will then be forwarded to the appropriate decision making body.
