XSym 2004

Second International XML Database Symposium (1,5 day - 29-30 August 2004)

The theme of the XML Database Symposium (XSym) is everything in the intersection of Database and XML Technologies. Today, we see growing interest in using these technologies together for many web-based and database-centric applications. XML is being used to publish data from database systems to the Web by providing input to content generators for Web pages, and database systems are increasingly used to store and query XML data, often by handling queries issued over the Internet. As database systems increasingly start talking to each other over the Web, there is a fast growing interest in using XML as the standard exchange format for distributed query processing. As a result, many relational database systems export data as XML documents and import data from XML documents and provide query and update capabilities for XML data. In addition, so-called native XML database and integration systems are appearing on the database market, whose claim is to be especially tailored to store, maintain and easily access XML-documents. The goal of this symposium is to bring together academics, practitioners, users and vendors to discuss the use and synergy between the above-mentioned technologies. Many commercial systems built today are increasingly using these technologies together and it is important to understand the various research and practical issues. The wide range of participants will help the various communities understand both specific and common problems. This symposium will provide the opportunity for all involved to debate new issues and directions for research and development work in the future.




Workshop on Information Integration on the Web (1 day - 30 August 2004)

The explosive growth and popularity of the world-wide web has resulted in a huge number of information sources on the Internet and the promise of unprecedented information-gathering capabilities to lay users. Unfortunately, the promise has not yet been transformed into reality. While there are sources relevant to virtually any user's query, the morass of sources presents a formidable hurdle to effectively accessing the information. One way of alleviating this problem is to develop web-based information integration systems or agents, which take a user's query or request (e.g., monitor a site), and access the relevant sources or services to efficiently support the request. The purpose of this workshop is to bring together researchers that are working in a variety of areas that are all related to the larger problem of integrating information on the Web. This includes research in the areas of machine learning, data mining, automatic planning, constraint reasoning, databases, view integration, information extraction, semantic web, web services, and other related areas.




Second Workshop on Spatio-Temporal Database Management (1 day - 30 August 2004)

The one-day Second Workshop on Spatio-Temporal Database Management will bring together leading researchers and developers in the area of spatio-temporal databases in order to discuss state-of-the-art as well as novel research in spatio-temporal databases. In the spirit of a workshop, submission of novel ideas and positions that can spark discussion among the attendees are strongly encouraged. The workshop is intended to serve as a forum for disseminating research and experience in this rapidly growing area.




Secure Data Management in a Connected World (1 day - 30 August 2004)

Concepts like ubiquitous computing and ambient intelligence that exploit increasingly interconnected networks and mobility put new requirements on data management. An important element in the connected world is that data will be accessible anytime anywhere. This also has its downside in that it becomes easier to get unauthorized data access. Furthermore, it will become easier to collect, store, and search personal information and endanger peoples' privacy. As a result security and privacy of data becomes more and more of an issue. Therefore, secure data management, which is also privacy-enhanced, turns out to be a challenging goal that will also seriously influence the acceptance of ubiquitous computing and ambient intelligence concepts by society. Aim of the workshop is to bring together people from the security research community and data management research community in order to exchange ideas on the secure management of data in the context of emerging networked services and applications. The workshop will provide forum for discussing practical experiences and theoretical research efforts that can help in solving these critical problems in secure data management. Authors from both academia and industry are invited to submit papers presenting novel research on the topics of interest.




International Workshop on Data Management for Sensor Networks (1 day - 30 August 2004)

The workshop will focus on the challenges of data processing and management in networks of remote, wireless, battery-powered sensing devices (sensor networks). The power-constrained, lossy, noisy, distributed, and remote nature of such networks means that traditional data management techniques often cannot be applied without significant re-tooling. Furthermore, new challenges associated with acquisition and processing of live sensor data mean that completely new database techniques must also be developed.


DBISP2P 2004

Second International Workshop On Databases, Information Systems and Peer-to-Peer Computing (1,5 day - 29-30 August 2004)

The aim of this second workshop is to continue exploring the promise of P2P to offer exciting new possibilities in distributed information processing and database technologies. The realization of this promise lies fundamentally in the availability of enhanced services such as structured ways for classifying and registering shared information, verification and certification of information, content distributed schemes and quality of content, security features, information discovery and accessibility, interoperation and composition of active information services, and finally market-based mechanisms to allow cooperative and non cooperative information exchanges. The P2P paradigm lends itself to constructing large scale complex, adaptive, autonomous and heterogeneous database and information systems, endowed with clearly specified and differential capabilities to negotiate, bargain, coordinate and self-organize the information exchanges in large scale networks. This vision will have a radical impact on the structure of complex organizations (business, scientific or otherwise) and on the emergence and the formation of social communities, and on how the information is organized and processed. The P2P information paradigm naturally encompasses static and wireless connectivity, and static and mobile architectures. Wireless connectivity combined with the increasingly small and powerful mobile devices and sensors pose new challenges as well as opportunities to the database community. Information becomes ubiquitous, highly distributed and accessible anywhere and at any time over highly dynamic, unstable networks with very severe constraints on the information management and processing capabilities. What techniques and data models may be appropriate for this environment, and yet guarantee or approach the performance, versatility and capability that users and developers come to enjoy in traditional static, centralized and distributed database environment? Is there a need to define new notions of consistency and durability, and completeness, for example? The proposed workshop will build on the success of the first one. It will concentrate on exploring the synergies between current database research and P2P computing. It is our belief that database research has much to contribute to the P2P grand challenge through its wealth of techniques for sophisticated semantics-based data models, new indexing algorithms and efficient data placement, query processing techniques and transaction processing. Database technologies in the new information age will form the crucial components of the first generation of complex adaptive P2P information systems, which will be characterized by their ability to continuously self-organize, adapt to new circumstances, promote emergence as an inherent property, optimize locally but not necessarily globally, deal with approximation and incompleteness. This workshop will also concentrate on the impact of complex adaptive information systems on current database technologies and their relation to emerging industrial technologies such as IBM's autonomic computing initiative.



SWBD 2004


2nd International Workshop on Semantic Web and Databases (1,5 day - 29-30 August 2004)

The Semantic Web is a key initiative being promoted by the World Wide Web Consortium (W3C) as the next generation of the current web. The objective of this workshop is to discuss database and information system applications that use semantics and to gain insight into the evolution of semantic web technology. Early commercial applications that make use of machine-understandable metadata range from information retrieval to Web-enabling of old-tech IBM 3270 sessions. Current developments include metadata-based Enterprise Application Integration (EAI) systems, data modeling solutions, and wireless applications. Machine-understandable metadata is emerging as a new foundation for component-based approaches to application development. Within the context of reusable distributed components, Web services represent the latest architectural advancement. These two concepts can be synthesized providing powerful new mechanisms for quickly modeling, creating and deploying complex applications that readily adapt to real world need. We welcome submissions that describe applications which are trying to achieve the above goal through the use of specifications such as WSDL, UDDI, SOAP, ebXML, XML/RDF, possibly in conjunction with transformation languages such as XSLT, RuleML, etc. We invite submissions that discuss real applications (piloted, deployed, robust prototypes) attacking real world problems in the Semantic Web arena today instead of the future. This potentially means very pragmatic decisions (e.g., executable agents that run in the context of graph-based application models) caused by the limitations of today's technology (e.g., are there robust/scalable XML/RDF parsers, stores, and inference engines?). Submissions that also address issues related to the business aspects, e.g., is there a market?, is there a sustainable value proposition?, what is the business model?, etc., will also be considered.




5th VLDB Workshop on Technologies for E-Services (1,5 day - 29-30 August 2004)

VLDB-TES'2004 is the fifth workshop in a successful series of annual workshops on technologies for E-Services, which have been held in conjunction with the International Conference on Very Large Data Bases. E-Services and Web Services have emerged as an effective technology for the automation of application integration across networks and organizations. They are supported by a large number of EAI and B2B automation platforms and are being heavily used in many corporations. Despite the early success, there are still many issues that need to be addressed to make integration easier, faster, cheaper, and more manageable. For examples, many standards are still immature or lack the necessary consensus to be widely adopted, development and runtime support is still far away from the level we are used to in traditional middleware, security standard is still evolving, and the service management angle is an area yet to be explored and exploited. The objective of VLDB-TES'04 is to bring together researchers, practitioners, and users to exchange new ideas, developments and experiences on issues related to E-Services. Unlike previous editions of TES, this year's edition is specifically focused on (a) innovative research work that may still be early in results, and (b) practical experiences in applying E-Service or Web Service technologies. Although we do encourage submissions that report on research results, we would also like to stimulate submissions that describe work in progress or ideas that have not yet been fully developed, but that the author feel have potential to make an impact. To this end, we would also like to solicit submissions of short papers (about 1500 words, or about 5 pages) that succinctly portray the issues, approaches, or practical experiences.
