The Eighth International Conference on Extending Database Technology, EDBT 2002, was held in Prague, Czech Republic, March 25-27, 2002. It marks the 50th anniversary of Charles University's Faculty of Mathematics and Physics and is the most recent in a series of conferences dedicated to the dissemination and exchange of the latest advances in data management. Previous conferences occurred in Konstanz, Valencia, Avignon, Cambridge, Vienna, and Venice. The topical theme of this year's conference is Data Management in the New Millennium, which encourages the community to see beyond the management of massive databases by conventional database management systems and to extend database technology to support new services and application areas. The intention is to spur greater interest in more integrated solutions to user problems, which often implies the consideration of data management issues in entire information systems infrastructures. There is data (almost) everywhere, and data access is needed (almost) always and everywhere. New technologies, services, and app- cations that involve the broader notion of data management are emerging more rapidly than ever, and the database community has much to o?er. The call for papers attracted numerous submissions, including 207 research papers, which is a new record for EDBT. The program committee selected 36 research papers, 6 industrial and applications papers, 13 software demos, and 6 tutorials for presentation at the conference. In addition, the conference program includes three keynote speeches, by Jari Ahola, Ian Horrocks, and Hans-J*org Schek, and a panel.

The 9th International Conference on Extending Database Technology, EDBT 2004, was held in Heraklion, Crete, Greece, during March 14-18, 2004. The EDBT series of conferences is an established and prestigious forum for the exchange of the latest research results in data management. Held every two years in an attractive European location, the conference provides unique opp- tunities for database researchers, practitioners, developers, and users to explore new ideas, techniques, and tools, and to exchange experiences. The previous events were held in Venice, Vienna, Cambridge, Avignon, Valencia, Konstanz, and Prague. EDBT 2004 had the theme "new challenges for database technology," with the goal of encouraging researchers to take a greater interest in the current exciting technological and application advancements and to devise and address new research and development directions for database technology. From its early days, database technology has been challenged and advanced by new uses and applications, and it continues to evolve along with application requirements and hardware advances. Today's DBMS technology faces yet several new challenges. Technological trends and new computation paradigms, and applications such as pervasive and ubiquitous computing, grid computing, bioinformatics, trust management, virtual communities, and digital asset management, to name just a few, require database technology to be deployed in a variety of environments and for a number of di?erent purposes. Such an extensive deployment will also require trustworthy, resilient database systems, as well as easy-to-manage and ?exible ones, to which we can entrust our data in whatever form they are.
