Since 1980, BNCOD conferences have provided an opportunity for researchers to present and discuss advances in research on database systems and in the deployment of database technology. Contributions have been made to the plotting of new directions in the dev- opmentof the technologyand inthe explorationofopportunitiesand challenges. TheProgrammeCommitteeofBNCOD2006soughtto continuethispattern, andthisyearwechosetoplacespecialemphasison“?exibilityandperformance.” The idea is to look at challenges and developments from these two complem- tary and sometimes competitive directions. In practice, there is often a ‘tig- rope’ to be walked between the two — keeping a balance is clearly important. However,this is sometimes overlooked,and sometimes a focus on one side or the other cannot be avoided. Authors from 16 countries contributed a total of 58 submissions to the m- bers of the Programme Committee. Each submission was evaluated by three members on the basis of originality,technicalquality, presentationand relevance to BNCOD. As a result we have selected 12 full, 6 short and 13 poster papers whichappearinthispublishedproceedingsvolumealongwiththeinvitedpapers. Some of the papers considered exclusively performance-related issues, and others were focussed on the ?exibility side. A few sought to address the balance directly. The papers were organized into six presentation sessions and a poster session. We summarize the papers by session below.
