In many of nowadays web-based environments for electronic marketing and commerce, that present large multimedia product and service catalogues, it becomes more and more difficult to provide naive end users, such as private consumers or commercial business partners, with intuitive user interfaces to access the large multimedia collections describing the presented products and services. The same holds for marketing managers and other employees responsible for managing and maintaining the large and constantly changing set of multimedia information chunks and fragments contained in these collections. As a consequence, many efforts are devoted to improve the quality of the interaction between users and databases. Virtual Reality (VR) techniques are a promising interaction paradigm particularly suited to novice and/or occasional users. The users are facilitated in the database navigation since the system proposes them an environment that reproduces a real situation and gives the possibility of interacting by manipulating objects that have a direct correspondence with known objects.
Both the way we look at data, through a DBMS, and the nature of data we ask a DBMS to manage have drastically evolved over the last decade, moving from text to images (and to sound to a lesser extent). Visual representations are used extensively within new user interfaces. Powerful visual approaches are being experimented for data manipulation, including the investigation of three dimensional display techniques. Similarly, sophisticated data visualization techniques are dramatically improving the understanding of the information extracted from a database. On the other hand, more and more applications use images as basic data or to enhance the quality and richness of data manipulation services. Image management has opened a wide area of new research topics in image understanding and analysis. The IFIP 2.6 Working Group on Databases strongly believes that a significant mutual enrichment is possible by confronting ideas, concepts and techniques supporting the work of researcher and practitioners in the two areas of visual interfaces to DBMS and DBMS management of visual data. For this reason, IFIP 2.6 has launched a series of conferences on Visual Database Systems. The first one has been held in Tokyo, 1989. VDB-2 was held in Budapest, 1991. This conference is the third in the series. As the preceding editions, the conference addresses researchers and practitioners active or interested in user interfaces, human-computer communication, knowledge representation and management, image processing and understanding, multimedia database techniques and computer vision.
The visual way of expressing and comprehending information is perhaps the most ancient, immediate and effective way. Image processing and database technologies came of age during the Eighties, though a new challenge arose from the need to handle not only the complexity of pictures, but also a large volume of pictures. Extending database technologies to capture visual aspects is an exciting new research area. This second volume highlights the latest results from leading laboratories all over the world, identifying new research directions. Main subject areas include: theory of spatial representations; image indexing and query techniques; visual and multimedia data structures; visual interfaces and object oriented approaches; and access and search methodologies on moving pictures.
The large amount and complex structure of visual information make visual database systems storage- and computation-intensive. However, recent advances in memory size and processing power make the practical application of visual databases a reality. New areas covered in this volume include pictorial databases, multimedia databases, object-oriented databases, visual structures, visual data models, model-driven approach, solid model-based databases, database design, prototyping and user interfaces.

Database Systems with Case Studies, covers exactly what students needs to know in an introductory database system course. This book focuses on database design and exposes students to a variety of approaches for getting the Data Model right. The book addresses issues related to database performance (Query Processing) and Transaction Management for multi-user environments. This book also introduces non-relational XML format to students. The approach taken to teach the topics is through introduction of many real-world enterprise database case studies and practice problems. The case studies are selected based on modern application areas, keeping the student’s interest in mind. The book provides hands-on experience of database design issues with several ready-made lab exercises. For grading students’ understanding of the topics, several challenging assignments are also provided at the end of chapters. Multiple-choice self-tests are provided for formative assessment throughout the book. The book is suitable for the undergraduate students of Computer Science and Engineering, Information Technology, and students of Computer Applications (BCA/MCA). Key features • All the topics are illustrated with practical examples. • Topics like Entity-Relationship diagram (ERD), are discussed with Diagrams and Visual Aids. • Students are exposed to the various approaches for determining data requirements. • Structured Query Language (SQL) examples are worked with scripts, results and solutions. • Exclusive lab exercises on SQL, can be used as assignments.
A collection of 69 papers which were presented at the IS&T/SPIE Electronic Imaging Symposium, 1999. They appear in 13 sessions on subjects such as: image retrieval applications; multimedia management and retrieval systems; video retrieval; and image browsing.

This book brings together two different subjects, computational intelligence and multimedia, to stress the expanding importance of these two areas for future technological development. The 90-plus papers presented here--a selection of presentations from the September 1999 conference--address various aspects of agent- based systems, artificial neural networks, evolutionary algorithms, hybrid systems, image and signal processing, rough sets/logic synthesis, knowledge-based engineering, memory, storage, retrieval, pattern recognition, formal models for multimedia, telecommunications, and virtual reality.
