Summary

This Dagstuhl Seminar brought together 37 researchers from 14 countries across disciplines that study data warehousing. The seminar can be seen as a successor of the Dagstuhl Perspectives Workshop 04321 ``Data Warehousing at the Crossroads'' (http://www.dagstuhl.de/04321) co-arranged by one of the organizers in 2004. After seven years (in 2011), we felt that it was time to take stock again, determine the status quo, and reflect on the future of data warehousing. Further, the seminar in 2004 was a perspectives workshop with the exclusive goal of predicting the possible future direction of data warehousing and OLAP. This seminar has a different scope and mainly dealt with current and recent research results. This does not exclude to look into the future and to determine what the field has achieved in the meantime.

The participants of the seminar were clustered around five thematic areas as follows

  • Real-Time Data Warehouses and Business Intelligence,
  • Spatio-Temporal Data Warehousing,
  • Situational Business Intelligence,
  • Query Processing in Data Warehousing, and
  • Knowledge Extraction and Management in Data Warehouses.

Tuesday and Thursday were devoted to parallel working groups, each group discussing the state of the art in its thematic area and identifying the open questions. The organizers asked to each group to answer the following four questions

  • Identify most pressing research issues.
  • Is the topic purely industrial or also academic?
  • Where do you expect to be 5 years from now?
  • What would you want a new PhD student to work on?

Further, longer research presentations were given within each group for focusing the groups' work around a common approach. Each group presented a short ongoing report of the work realized in Wednesday morning, and a final presentation of their results on Friday morning.

It is worth noting that the Data Warehouse domain is both an active research domain but also drives a very intense activity in the industrial world. One objective of the seminar was also to establish bridges between these two communities. The seminar attracted participants from major companies active in the Data Warehouse domain (Sybase, HP, IBM, and EMC). Another concrete step in this respect was an industrial presentation given on Wednesday morning by Knut Stolze, from IBM Germany.

All five groups have committed to produce a paper to be published in a special issue of a journal. After discussion among the participants, the organizers started negotiating with different journals about this possibility, and finally the journal chosen was the International Journal of Data Warehouse and Mining. It is expected that the papers will be submitted to the journal in January 2012 so that the publication of the special issue will be at the end of 2012.
