The sequence of East ecu meetings on Advances in Databases and knowledge platforms (ADBIS) is a longtime and prestigious discussion board for the alternate of the most recent learn leads to facts administration. It presents certain possibilities for database researchers, practitioners, builders, and clients from East ecu international locations to discover new rules, suggestions, and instruments, and to interchange reports with colleagues from the remainder of the realm. This quantity includes the complaints of the eleventh ADBIS convention, held in Varna, Bulgaria, September 29 – October three, 2007. The convention incorporated three keynote talks, 36 examine papers in thirteen classes, and a pair of tutorials. Twenty-tree of the study papers in addition to papers or prolonged abstracts for the keynote talks are integrated the following; the rest papers look in neighborhood lawsuits. individual individuals of the database and information-retrieval groups brought the 3 keynotes. Timos Sellis, a professional within the zone of multidimensional indexing and information warehousing, analyzed the complete lifecycle of ETL workflows, from specification to optimized execution, delivering suggestions in addition to destiny demanding situations. Gerhard Weikum, a pace-setter of numerous efforts falling on the intersection of databases and knowledge retrieval, mentioned the emergence of a number of “Webs” and the way those can be harvested and hunted for wisdom. eventually, Paolo Atzeni, recognized for a number of contributions to database concept, addressed the perennial challenge of schema and knowledge translation within the context of rising version administration platforms and defined a number of learn demanding situations that emerge.

Moreover, [12] does not come within the web context. At the opposite, [22] defines an ontology of protocols devoted to business processes, and address their coordination through their composition. It also explains how to compile them into executable rules. However, [22] does not address the selection issue and does not provide a protocol classification useful to help the workflow partners in selecting the appropriate protocol according to the execution context. Our research efforts are now focused on protocol execution.
