Modern intra- and inter-enterprise collaboration requires access to information spread over multiple autonomous and heterogeneous data sources. In this paper we present a loosely coupled multidatabase architecture enhanced with P2P concepts. It achieves a reasonable tradeoff between autonomy and information sharing among both, permanently available and volatile data sources. Each data node decides autonomously which kind of information to share. Data availability, query performance, and up-to-dateness on each participating data node is improved using a push-based replication strategy, which propagates data modifications over multiple nodes.
