Advances in Databases

This volume contains the proceedings of the eleventh BritishNational Conference on Databases, held at Keele University,England. A dominant themein the volume is the provision ofthe means to enhance the capabilities of databases to handleinformation that has a rich semantic structure. A majorresearch question is how to achieve such a semantic scale-upwithout sacrificing performance. There are currently twomain paradigms within which it is possible to proposeanswers to this question, deduction-oriented andobject-oriented. Both paradigms are well represented in thiscollection, with the balance in the direction of thedeductive approach, which is followed by both the invitedpapers, by Michael Freeston from the EuropeanComputer-Industry Research Centre in Munich and CarloZaniolo from the University of California at Los Angeles. Inaddition, the volume contains 13 full papers selected from atotal of36 submissions.
