Researchers in data management have recently recognized the importance of a new class of data-intensive applications that requires managing data streams, i.e., data composed of continuous, real-time sequence of items. Streaming applications pose new and interesting challenges for data management systems. Such application domains require queries to be evaluated continuously as opposed to the one time evaluation of a query for traditional applications. Streaming data sets grow continuously and queries must be evaluated on such unbounded data sets. These, as well as other challenges, require a major rethink of almost all aspects of traditional database management systems to support streaming applications. Stream Data Management comprises eight invited chapters by researchers active in stream data management. The collected chapters provide exposition of algorithms, languages, as well as systems proposed and implemented for managing streaming data. Stream Data Management is designed to appeal to researchers or practitioners already involved in stream data management, as well as to those starting out in this area. This book is also suitable for graduate students in computer science interested in learning about stream data management.

Modern applications are both data and computationally intensive and require the storage and manipulation of voluminous traditional (alphanumeric) and nontraditional data sets (images, text, geometric objects, time-series). Examples of such emerging application domains are: Geographical Information Systems (GIS), Multimedia Information Systems, CAD/CAM, Time-Series Analysis, Medical Information Sstems, On-Line Analytical Processing (OLAP), and Data Mining. These applications pose diverse requirements with respect to the information and the operations that need to be supported. From the database perspective, new techniques and tools therefore need to be developed towards increased processing efficiency. This monograph explores the way spatial database management systems aim at supporting queries that involve the space characteristics of the underlying data, and discusses query processing techniques for nearest neighbor queries. It provides both basic concepts and state-of-the-art results in spatial databases and parallel processing research, and studies numerous applications of nearest neighbor queries.

This volume comprises papers from the following ?ve workshops that were part of the complete program for the International Conference on Extending Database Technology (EDBT) held in Heraklion, Greece, March 2004: * ICDE/EDBT Joint Ph. D. Workshop (PhD) * Database Technologies for Handling XML-information on the Web (DataX) * Pervasive Information Management (PIM) * Peer-to-Peer Computing and Databases (P2P&DB) * Clustering Information Over the Web (ClustWeb) Together, the ?ve workshops featured 61 high-quality papers selected from appr- imately 180 submissions. It was, therefore, dif?cult to decide on the papers that were to beacceptedforpresentation. Webelievethattheacceptedpaperssubstantiallycontribute to their particular ?elds of research. The workshops were an excellent basis for intense and highly fruitful discussions. The quality and quantity of papers show that the areas of interest for the workshops are highly active. A large number of excellent researchers are working on the aforementioned ?elds producing research output that is not only of interest for other researchers but also for industry. The organizers and participants of the workshops were highly satis?ed with the output. The high quality of the presenters and workshop participants contributed to the success of each workshop. The amazing environment of Heraklion and the location of the EDBT conference also contributed to the overall success. Last, but not least, our sincere thanks to the conference organizers - the organizing team was always willing to help and if there were things that did not work, assistance was quickly available.

We have described the development of a new micro-payment system, NetPay, f- turing different ways of managing electronic money, or e-coins. NetPay provides an off-line, anonymous protocol that supports high-volume, low-cost electronic trans- tions over the Internet. We developed three kinds of e-wallets to manage coins in a NetPay-based system: a sever-side e-wallet allowing multiple computer access to- coins; a client-side e-wallet allowing customer PC management of the e-coins, and a cookie-based e-wallet cache to improve performance of the client-side e-wallet c- munication overhead. Experiences to date with NetPay prototypes have demonstrated it provides an effective micro-payment strategy and customers welcome the ability to manage their electronic coins in different ways.

The IFIP TC-6 9th International Conference on Personal Wireless Communi- tions, PWC 2004 is the main conference of the IFIP Working Group 6. 8, Mobile and Wireless Communications. The ?eld of personal wireless communications is steadily growing in imp- tance,fromanacademic,industrialandsocietalpointofview. Thedroppingcost of WLAN and short-range technologies such as Bluetooth and Zigbee is causing the proliferation of personal devices and appliances equipped with radio int- faces. Together with the gradual deployment of powerful wireless infrastructure networks, such as 3G cellular systems and WLAN hotspots, the conditions are being created for a?ordable ubiquitous communication involving virtually any artifact. This enables new application areas such as ambient intelligence where a world of devices, sensors and actuators surrounding us use wireless technology to create systems that assist us in an unobtrusive way. It also allows the - velopment of personal and personalized environments that accompany a person whereverheorshegoes. ExamplesarePersonalAreaNetworks(PAN)physically surrounding a person, and personal networks with a potentially global reach. PWC 2004 re?ects these developments, which are happening on a global scale. Researchers from all over the world, and in particular a large number from Asia, made contributions to the conference. There were 100 submissions. After a thorough reviewing process, 25 full papers and 13 short papers were retained for presentation in the technical sessions. The papers cover the whole range of wireless and mobile technologies: cellular systems, WLAN, ad hoc and sensor networks, host and network mobility, transport protocols for wireless systems, and the physical layer.

The 11th Conference "e;Artificial Intelligence: Methodology, Systems, Applications - Semantic Web Challenges"e; (AIMSA 2004) continued successfully pursuing the main aim of the AIMSA series of conferences - to foster the multidisciplinary community of artificial intelligence researchers, embracing both the theoretic underpinnings of the field and the practical issues involved in development, deployment, and maintenance of systems with intelligent behavior. Since the first conference in 1984 AIMSA has provided an ideal forum for international scientific exchange between Central/Eastern Europe and the rest of the world and it is even more important nowadays in the uni- ing Europe. The current AIMSA edition is focused on Semantic Web methods and technologies. The Internet is changing the everyday services landscape, and the way we do things in almost every domain of our life. Web services are rapidly becoming the enabling technology of today's e-business and e-commerce systems, and will soon transform the Web as it is now into a distributed computation and application framework. The emerging Semantic Web paradigm promises to annotate Web artefacts to enable automated reasoning about them. When applied to e-services, the paradigm hopes to provide substantial automation for activities such as discovery, invocation, assembly, and monitoring of e-services. One hundred and seventy-six interesting papers were submitted to the conference.

This year marked the coming of age of the British National Conference on Databases with its 21st conference held at Heriot-Watt University, Edinburgh, in July 2004. To mark the occasion the general theme of the conference was "e;When Data Is Key"e;, reflecting not only the traditional key awarded on a 21st birthday, but also the ev- growing importance of electronic data management in every aspect of our modern lives. The conference was run as part of DAMMS (Data Analysis, Manipulation, Management and Storage) Week, which included a number of co-located and complementary conferences and workshops, including the 2nd Workshop on Teaching, Learning and Assessment in Databases (TLAD2), the BNCOD BioInformatics Workshop, and the 1st International Conference on the Future of Consumer Insight Developments in Retail Banking. The aim of this co-location was to develop synergies between the teaching, research and commercial communities involved in all aspects of database activities, and to use BNCOD as a focus for future synergies and developments within these communities. Although this is entitled the British National Conference on Databases, BNCOD has always had an international focus, and this year more than most, with the majority of the papers submitted and accepted coming from outwith the UK.

th CAiSE 2004 was the 16 in the series of International Conferences on Advanced Information Systems Engineering. In the year 2004 the conference was hosted by the Faculty of Computer Science and Information Technology, Riga Technical University, Latvia. Since the late 1980s, the CAiSE conferences have provided a forum for the presentation and exchange of research results and practical experiences within the ?eld of Information Systems Engineering. The conference theme of CAiSE 2004 was Knowledge and Model Driven Information Systems Engineering for Networked Organizations. Modern businesses and IT systems are facing an ever more complex en- ronment characterized by openness, variety, and change. Organizations are - coming less self-su?cient and increasingly dependent on business partners and other actors. These trends call for openness of business as well as IT systems, i.e. the ability to connect and interoperate with other systems. Furthermore, organizations are experiencing ever more variety in their business, in all c- ceivable dimensions. The di?erent competencies required by the workforce are multiplying. In the same way, the variety in technology is overwhelming with a multitude of languages, platforms, devices, standards, and products. Moreover, organizations need to manage an environment that is constantly changing and where lead times, product life cycles, and partner relationships are shortening. ThedemandofhavingtoconstantlyadaptITtochangingtechnologiesandbu- ness practices has resulted in the birth of new ideas which may have a profound impact on the information systems engineering practices in future years, such as autonomic computing, component and services marketplaces and dynamically generated software.

Welcome to MMNS 2003. Multimedia services over IP networks are proliferating at an enormous speed. There is also increasing demand for solutions that provide assured levels of s- vice quality. All of these require novel paradigms, models, and architectures for realizing integrated end-to-end service management rather than managing n- work elements in isolation. Providing scalable Quality of Service (QoS) while maintaining fairness, along with secure and optimal network resource mana- ment, are key challenges for the future Internet. These challenges apply to both ?xed and wireless networks. This book contains all of the papers presented at the 6th IFIP/IEEE - ternational Conference on Management of Multimedia Networks and Services (MMNS 2003) hosted by The Queen's University of Belfast, Northern Ireland, September 7-10, 2003. MMNS 2003 follows the successful conferences held in Santa Barbara (2002), Chicago (2001), Fortaleza, Brazil (2000), Paris (1998), and Montreal (1997). MMNS uses single-track presentations, which provide an intimate setting for discussion and debate. The conference is known for its high quality papers from various research communities. In just six years, MMNS has established itself as one of the premier conferences focusing on the management of multimedia networks and services. The conference objective is to bring - gether researchers working in all facets of network and service management as applied to broadband networks and multimedia services.

iTrust is an Information Society Technologies (IST) working group, which started on 1st of August, 2002. The working group is being funded as a concerted action/ thematic network by the Future and Emerging Technologies (FET) unit of the IST program. The aim of iTrust is to provide a forum for cross-disciplinary investigation of the application of trust as a means of establishing security and con?dence in the global computing infrastructure, recognizing trust as a crucial enabler for meaningful and mutually bene?cial interactions. The proposed forum is intended to bring together researchers with a keen interest in complementary aspects of trust, from technology-oriented disciplines and the ?elds of law, social sciences, and philosophy. Hence providing the c- sortium participants (and the research communities associated with them) with the common background necessary for advancing toward an in-depth underst- ding of the fundamental issues and challenges in the area of trust management in open systems. Broadly the initiative aims to: - facilitate the cross-disciplinary investigation of fundamental issues underp- ning computational trust models by bringing together expertise from te- nology oriented sciences, law, philosophy, and social sciences - facilitate the emergence of widely acceptable trust management processes for dynamic open systems and applications - facilitate the development of new paradigms in the area of dynamic open systems which e?ectively utilize computational trust models - help the incorporation of trust management elements in existing standards.

Images and video play a crucial role in visual information systems and multimedia. There is an extraordinary number of applications of such systems in entertainment, business, art, engineering, and science. Such applications often involved large image and video collections, and therefore, searching for images and video in large collections is becoming an important operation. Because of the size of such databases, efficiency is crucial. We strongly believe that image and video retrieval need an integrated approach from fields such as image processing, shape processing, perception, database indexing, visualization, and querying, etc. This book contains a selection of results that was presented at the Dagstuhl Seminar on Content-Based Image and Video Retrieval, in December 1999. The purpose of this seminar was to bring together people from the various fields, in order to promote information exchange and interaction among researchers who are interested in various aspects of accessing the content of image and video data. The book provides an overview of the state of the art in content-based image and video retrieval. The topics covered by the chapters are integrated system aspects, as well as techniques from image processing, computer vision, multimedia, databases, graphics, signal processing, and information theory. The book will be of interest to researchers and professionals in the fields of multimedia, visual information (database) systems, computer vision, and information retrieval.
