Abstract

Asynchronous interactions are becoming more and more important in the realization of complex B2B Web applications, and Web services are at the moment the most innovative and well-established implementation platform for communication between applications. This paper studies the existing business protocols for Web services interactions, compares their expressive power, extracts a set of patterns for implementing asynchrony, studies the trade-offs and the typical usage scenarios of the various patterns, and finally proposes a sample application that has been implemented based on these patterns. The application has been designed using a high-level modeling language for Web applications, thus showing that the studied patterns can be applied at a conceptual level as well as directly at implementation level.
