The workshop will be accompanied by prominent professors and researchers in the field of database technology. These accompanying professors will participate actively and contribute to the discussions. The workshop language is English.
DataX'06 -- Database Technologies for Handling XML Information on the Web
Sunday, March 26, 2006 (pre-conference)
Today's horizons of the database field appear without limits. Peer-to-peer architectures, the Grid, personal information systems, pervasive and ubiquitous computing, networked sensors, biomedical informatics, virtual digital libraries, semantic virtual communities, database services and trust management are few samples of the great challenges that drive research and development of the next generation of database technology. Our belief is that XML is one of the main means towards this new generation. Following the experience of the dataX workshop at EDBT 2004, the 2006 edition of the workshop will discuss new and interesting applications and integrations of XML and database technologies.
The goal of the workshop is to bring together academics, practitioners, users, and vendors to discuss the recent achievements, the relevant problems and open issues related to the combination of database and XML technologies in all these environments. The workshop will provide the opportunity to debate new issues and directions for research and development work in the future.
Incompleteness and Inconsistency in Databases
Sunday, March 26, 2006 (pre-conference)
Database textbooks generally explain that integrity constraints should be satisfied at all times because they capture the set of all legal databases. Nevertheless, data inconsistency is a phenomenon that often occurs in practice. The most common reason for inconsistency is the need to integrate distributed, independent data sources: different databases that are consistent by themselves can contain conflicting tuples. The conflicts are revealed only when the tuples are brought together in an integrated database. In such situations, it is of practical importance to know how to deal with violations of integrity constraints. In general, there is no single best way to restore consistency, leaving us with a multitude of possible repairs. Even when we do not know the right repair, we can still try to prevent query answers from containing incorrect tuples. This idea is known as consistent query answering (CQA).
A similar concept arises in the context of incomplete databases: when an incompletely specified database can be completed in more than one way, we may want to restrict query answers to contain only the tuples that are in the query answer in each possible completion. Incomplete databases can arise, for example, when the data exchange rules between a source and a target database only partially determine the target. Also, an incomplete database may play a role similar to a set of repairs, representing different ways of solving existing data conflicts.
Another related area is that of uncertainty handling, where numeric probability factors are associated with data. Such data represent observations and arise in sensor networks or distributed databases. For example, the position of a moving object can only be ascertained with some degree of probability.
This EDBT workshop is a new opportunity to bring together database researchers working on inconsistency, incompleteness, and uncertainty to review recent progress and outline future research directions. The focus of the workshop will be primarily on semantic and computational issues arising in the representation and querying of inconsistent, incomplete, and uncertain databases.
Information Integration in Healthcare Applications (IIHA)
Sunday, March 26, 2006 (pre-conference)
Healthcare information systems continuously have to be adapted to new requirements, standards, laws, etc. Cost pressure is massively increasing, and at the same time, system complexity is growing. This constantly changing environment is also characterized by highly interdisciplinary processes which depend on timely providing patient related information at the point of care in order to prevent medical errors. In addition, medical knowledge should be provided in a way that enables effective decision support for clinicians. Huge amounts of data with increasingly complex data structures are created in the course of this process, and legacy systems have to be integrated. The core challenge is to establish flexible and responsive IT infrastructures that are capable of effectively adapting to changing requirements.
Information integration thus is a key factor for healthcare applications, as most medical applications are determined by a huge variety of heterogeneous and independent health care institutions that have to share data. The continuity of medical processes has to be improved, and medical pathways will play an important role as integration backbone within institutions and across institutional borders.
In order to ensure efficient and high-quality patient treatment, data have to be exchanged between participating systems in a consistent and appropriate way. Various aspects have to be considered in order to support health care professionals in their clinical routine work. In addition, scientists need support for their (distributed) research.
IFIP Workshop on Semantics of a Networked World
Thursday, March 30, 2006 (post-conference)
IFIP The explosion in information exchange fostered by the success of the Web has led to the identification of semantics as a critical issue in the development of services providing data and information to users and applications worldwide. This newly designated conference series on "Semantics for the Networked World" unifies into a single framework the previous series on "Database Semantics" and "Visual Database Systems" that the IFIP WG 2.6 has been offering since 1985. The series intends to continue the exploration of novel emerging trends that raise challenging research issues related to the understanding and management of semantics. Each conference edition, in addition to soliciting contributions of generic relevance in the semantics domain, will focus on a specific theme that conveys exciting promises of innovation.
The theme for the 2006 edition is Semantics of sequence and time dependent data Sequence and time dependent data are distinguished by the important role played by order, in modelling and querying the data. For example, monitoring dynamic phenomena produces data that arrives as a stream of temporal observations, whose querying and analysis make essential use of its temporal or sequential nature. Data warehouses give considerable prominence to the temporal dimension for decision support. Applications in the biological and financial domains naturally model their data using sequences, and the mining of such data make critical use of this property.
Query Languages and Query Processing (QLQP-2006)
Thursday-Friday, March 30-31, 2006 (post-conference)
The development of database query languages, the investigation of semantics for query langauges as well as query processing and query optimization are established and permanent research areas. The development of new data models usually causes the development of new query languages, new requirements in application domains require an on-going improvement of existing query languages. The ever-growing amount of data as well as new architectures for database and information systems continously causes the development of new and of more sophisticated query processing and optimization techniques. Examples of such new directions range from new operators like ranking and approximations to translation techniques like XQuery to SQL and new query models such as continuous queries on streams and adaptive techniques for Grid and P2P systems.
The goal of this workshop is to foster the discussion on new challenges and direction of query languages and processing for the next decade.
2nd International Workshop on Pervasive Information Management (PIM 2006)
Thursday, March 30, 2006 (post-conference)
The first EDBT Workshop on Pervasive Data Management was held successfully at EDBT 2004. Since then, interest in pervasive information management has become even more pronounced both in academia and industry. The numbers of mobile devices in use keep growing at tremendous rates. On the one hand, this is true for rather powerful devices like PDAs and smartphones, on the other hand, very lightweight devices like sensors and RFID tags are starting to be deployed in considerable numbers. This development opens the doors for new application areas where information stemming from a multitude of different sources is used to satisfy user demands. However, data management for these applications is a complex task since it has to deal with the mobility of users, devices and data as well as the specifics of wireless connectivity and the resource restrictions many of these devices exhibit. Therefore, new solutions that consider all these dimensions are needed for pervasive data management.
Information becomes ubiquitous, highly distributed and at the same time accessible from everywhere at any time. However, accessing it takes place in highly dynamic and instable networks often using devices with limited I/O-capabilities and restricted power resources. Information obtained from different sources, among them sensors, needs to be integrated. From the user's point of view, all these difficulties should be invisible. Information access should be as similar to the one known from the desktop environment as possible.
This workshop will be a forum for presenting and discussing ideas, challenges, and opportunities for data management and data access technology in pervasive information systems. New and existing concepts and techniques shall be considered in the light of the rapidly increasing mobility of users and the great advances in system infrastructures, mobile devices, and sensor technologies. Research papers presenting theoretical results, perspective solutions, and practical developments are welcome. Position papers are also welcome and encouraged.
2nd International Workshop on Pattern Representation and Management (PaRMa'06)
Thursday, March 30, 2006 (post-conference)
The vast volumes of data in conventional form, in documents and in multimedia files demand for methods for the discovery of useful patterns from them. Such methods from the domain of knowledge discovery deliver patterns in the form of association rules, classifiers, clusters or time series. Similarly to the need for maintaining, retrieving and updating data, there is the same paramount need to administer patterns: To store them in databases in an efficient way and to provide appropriate query languages for retrieving them; to update them as new data reveal population drifts and to identify such population drifts; to design methods for the presentation, evaluation and comparison of patterns. In order to efficiently and effectively deal with patterns, academic groups and industrial consortiums have devoted efforts towards the modeling, storage, retrieval, analysis and manipulation of patterns with results mainly in the area of standards, inductive databases and pattern-base management systems. The workshop aims at bringing together researchers and practitioners in the area of pattern representation and management.
Reactivity on the Web
Friday, March 31, 2006 (post-conference)
Reactivity on the Web, the ability to detect simple and composite events that occur on the Web and respond in a timely manner, has recently emerged as an issue of concern in Web and Semantic Web circles such as the W3C and several international Semantic Web research initiatives such as REWERSE. Although a common perception of the Web is that of a distributed information system giving rise to access data in a read only manner, many Web-based systems need to have the capability to update data found at (local or remote) Web resources, to exchange information about events (such as executed updates), and to detect and react not only to simple events but also to complex, real-life situations. The issue of updating data plays an important role, for example, in e-commerce systems receiving and processing buying or reservation orders, and e-learning systems selecting and delivering teaching materials depending on the students' performances on tests. The issues of notifying, detecting, and reacting upon events of interest are now beginning to play an increasingly important role within business strategy on the Web and event-driven applications are being more widely deployed: Terms such as zero latency enterprise, the real-time enterprise and on-demand computing are being used to describe a vision in which events recognised anywhere within a business, can immediately activate appropriate actions across the entire enterprise and beyond. Businesses that are able to react to events quickly and take appropriate decisions are likely to have a competitive advantage.
The issue of automatic reaction in response to events of interest has its roots in the field of active databases; in particular, the issue of detecting composite events has received considerable attention. However, differences between (generally centralised) active databases and the Web, where a central clock and a central management are missing, give reasons for developing new approaches. Moreover, approaches that cope with existing and upcoming Semantic Web technologies (by gradually evolving together with these technologies) are more likely to leverage the Semantic Web endeavour. Along this line, of crucial importance for the Web and the Semantic Web is the lightness of technologies' usage (in particular the languages' usage) that should be approachable also by non-programmers.
The objectives of the workshop 'Reactivity on the Web' are to support and disseminate ongoing research work on Web reactivity, but also to offer a forum for communicating visionary ideas that could entail enhancements of the actual Web with (re)active capabilities.
