LETTER FROM THE GUEST EDITORS
It is our pleasure to present the eighth issue of Proceedings of the VLDB Endowment (PVLDB) Volume 6.
This issue contains five papers, all from the Research Track. Topics include data analytics, novel storage,
distributed query optimization, diversity complexity and data streams. These and other papers will be
presented at the VLDB 2013 Conference, to be held in Riva del Garda, Trento, Italy, August 26-30, 2013.
All of these papers were reviewed in a journal-style review and revision process with monthly year-round
submission cycles.
As Associate Editors, we have enjoyed overlooking the review process of the excellent papers accepted to
VLDB 2013. We thank the authors for their submissions and for their willingness to incorporate obtained
feedback in time. We also thank the Review Board for ensuring scientific and technical quality of the
papers with thorough reviews and on-time discussions. It has been a pleasure to work with an
outstanding set of editorial colleagues. We hope that this new process will continue in the next years.
These proceedings would not have been possible without the continuous involvement of our colleagues in
the research community. We are proud to be part of such a team and we look forward to seeing you in
Riva del Garda.
