It is our great pleasure to welcome you to the Fifth ACM Conference on Distributed Event Based Systems -- DEBS'11. This conference continues the tradition of its four predecessors, and the five editions of the DEBS workshops --- each held in conjunction with other major conferences, until it became the flagship conference of an emerging community. This community has been established during recent years and consists of researchers and practitioners who come from the distributed computing area (the "pub/sub" community), the event processing area, various sub-communities of the database area (active databases, data stream management and temporal databases), business process management and programming languages. This community also held two Dagstuhl seminars, and several other shared activities.
The call for papers solicited research contributions in three major umbrella topics: (1) Models, Architectures and Paradigms; (2) Middleware Infrastructures for Event-Based Computing; and (3) Applications, Experiences, and Requirements. The call for contributions to the research track attracted 95 submissions from around the globe. The research program committee accepted 23 papers that cover a variety of topics related to programming paradigms, languages, tools, system considerations, user interfaces, optimization of performance and more. In addition the industry track program committee accepted 10 papers that relate to implementation within event processing platforms and to applications and experience reports.
The conference also includes four keynote talks provided by: Christopher Bird, Donald F. Ferguson, Johannes Gehrke, and Calton Pu, one invited talk by Edward Epstein, and five tutorials, as well as a PhD workshop, poster and demo session, a DEBS challenge session and the first DEBS "gong show".
