摘要

Integration of multiple heterogeneous sources is crucial forefficient sharing and reuse of distributed data. An architecture for scalabledata integration of many autonomous data sources is presented. Inthe architecture peer-to-peer (P2P) mediators can be defined in terms ofeach other through object-oriented (OO) views. Query processing withscalable performance is important to make such an architecture usefulin practice. The focus of the described doctoral thesis is on query...
