We present the design of ObjectGlobe, a distributed and open query processor for Internet data sources. The goal of the ObjectGlobe project is to establish an open market place in which data and query processing capabilities can be distributed and used by any kind of Internet application. Furthermore, ObjectGlobe integrates cycle providers (i.e., machines) which carry out query processing operators. The overall picture is to make it possible to execute a query with --in principle-- unrelated query operators, cycle providers and data sources.
One of the main challenges in the design of such an open system is to ensure privacy and security. We discuss the ObjectGlobe security requirements, show how basic components such as the optimizer and runtime system need to be extended. Another challenge is quality of service (QoS) management so that users can constrain the costs and running times of their queries.

D. degrees in Computer Science from the University of Southern California in Los Angeles in 1981 and 1984. His research concentrates on optimization of advanced database systems and applications (e.g. data warehouses and decision-support query processing), on distributed data base systems and query processing, and on complex database application system performance analysis and tuning, in particular for the SAP R/3 system. Prof. Kemper has authored over 75 publications including three books on database systems.
Reinhard Braumandl (University of Passau) studied Computer Science at the University of Passau from 1992 to 1997. Since 1997, he has been a research assistant in the department for mathematics and computer science at the University of Passau. He is currently pursuing the Ph.D. degree. His research interests include query processing, performance analysis and QoS management in object-oriented and distributed databases.
