This book constitutes the refereed proceedings of the Second International Workshop on Electronic Commerce, WELCOM 2001, held in Heidelberg, Germany in November 2001. The 17 revised full papers presented together with two invited contributions were carefully reviewed and selected from 34 submissions. The papers are organized in topical sections on trade and markets, security and trust, auctions, profiling, and business interaction.
This book provides an in-depth description of event-based systems, covering topics ranging from local event matching and distributed event forwarding algorithms, through a practical discussion of software engineering issues raised by the event-based style, to state-of-the-art research in event-based systems like composite event detection and security. The authors offer a comprehensive overview, and show the power of event-based architectures in modern system design, encouraging professionals to exploit this technique in next generation large-scale distributed applications like information dissemination, network monitoring, enterprise application integration, or mobile systems.
