Quality of Service and Optimization in Data Integration Systems

: Due to the ever increasing impacts of globalization, people will/have to work on data which is distributed all around the world [LKK+ 97]. Query processing on the corresponding data sources is a key data processing task in most distributed applications and rather difficult to implement for interactive usage in an Internet scale environment. ObjectGlobe is a data integration system which enables interactive query processing in such an environment. The basic architecture of the ObjectGlobe system and its integrated quality of service (QoS) management component were developed in this dissertation and briefly summarized in this paper.
