Nontraditional Database Systems is the fifth volume in the Advanced Information Processing Technology series. It brings together the results of research carried out by the Japanese database research community in the field of nontraditional database systems. The book examines nontraditional types of applications, data types, systems and environments together with high-performance architecture to support nontraditional applications, such as web mining, data engineering and object processing.

This volume is the proceedings of the Second InternationalConference on Deductive and Object-Oriented Databases(DOOD). During the last decade, deductive andobject-oriented systems have received a great deal ofattention, but for the most part these two fields wereevolving independently of each other. Today there is a largebody of work suggesting that the deductive andobject-oriented paradigms complement each other.The object-oriented paradigm is characterized by its view ofthe data, whereby information is grouped around objects withcomplex internal structure accessed via methods. Thedeclarative paradigm is centered around the idea that datamanipulation must be done through a declarative, logic-basedlanguage. It is hoped that these two aspects, broughttogether in one system, will provide an integrated frameworkfora new database technology.The DOOD conference brings together researchers anddevelopers in the fields of deductive and object-orienteddatabases to stimulate technical discussion and acceleratethe integration of the two technologies. This volumecontains 28 contributed papers (selected from 98submissions) and two invited papers by world-renownedresearchers.

This book constitutes the strictly refereed post-conference proceedings of the International Conference on Worldwide Computing and Its Applications, WWCA'97, held in Tsukuba, Japan, in March 1997.The volume presents 15 revised full papers selected from 50 submissions as well as 15 revised invited papers by leading researchers in this emerging area and two keynotes. The papers are organized in topical sections on distributed programming languages and systems, distributed object environments, cooperative computation, collaboration support Systems, collaborative media, novel distributed applications, Internet and protocols, distributed system platforms, mobile computing, and application gateways.

This book constitutes the refereed proceedings of the Second International Conference on Worldwide Computing and Its Applications, WWCA'98, held in Tsukuba, Japan, in March 1998. This volume presents 14 invited and survey papers together with 20 papers selected by the conference committee. The volume is divided into topical sections on distributed objects, distributed componentware, distributed systems platforms, Internet technology, mobile computing, interculture technology, collaborative media, collaborative support, information discovery and retrieval, novel network applications.

Advances in Database Technologies(ADT) is a workshopseries designed to p- mote interaction and discussion among researchers and practitioners in speci?c topics related to advanced data modeling and database technologies. The ?rst ADT workshop was held in conjunction with the 17th International Conference on Conceptual Modeling (ER'98) in Singapore. It consisted of three small wo- shops,i.e.,the"InternationalWorkshoponDataWarehousingandDataMining" organized by Prof. Sham Navathe and Dr. Mukesh Mohania, the "International Workshop on Mobile Data Access" organized by Prof. Dik Lun Lee, and the "InternationalWorkshopon New DatabaseTechnologiesfor CollaborativeWork Support and Spatio-TemporalData Management" organizedby Prof.Yoshifumi Masunaga. These three small workshops were held simultaneously on 19 and 20 November, and the papers were jointly published in this ADT'98 proceedings. Wewouldliketo thankProf.ShamNavathe,Dr. MukeshMohania,Prof.Dik Lun Lee, Prof. Yoshifumi Masunaga and their program committees for wo- ing together to insure an excellent workshop program. The program co-chair of ER'98 Prof.Tok Wang Ling and his organizing committee members gave o- standing support to the workshops with the local arrangements, registration, publicity, and the preparationof the proceedings. Our special thanks go to Prof.

This volume presents the refereed proceedings of the East-European Conference on Advances in Databases and Information Systems and of the International Conference on Database Systems for Advanced Applications, ADBIS-DASFAA 2000, held jointly in Prague, Czech Republic in September 2000. The 27 revised papers presented together with one invited paper and the abstract of an invited talk were carefully reviewed and selected from 115 submissions. The papers present new results on a variety of current issues in database research and design with a certain emphasis on advanced applications in various fields.

This volume contains three keynote papers and 51 technical papers from contributors around the world on topics in the research and development of database systems, such as Data Modelling, Object-Oriented Databases, Active Databases, Data Mining, Heterogeneous Databases, Distributed Databases, Parallel Query Processing, Multi-Media Databases, Transaction Management Systems, Document Databases, Temporal Databases, Deductive Databases, User Interface, and Advanced Database Applications.

This volume contains technical papers and panel position papers selected from the proceedings of the International Symposium on Information Systems and Technologies for Network Society, held together with the IPSJ (information processing society of Japan) National Convention, in September 1997. Papers were submitted from all over the world, especially from Japan, Korea and China. Since these countries are believed to form one of the major computer manufacturing centers in the world, a panel on “Computer Science Education for the 21st Century” was set up. A special session on the Japanese project on Software Engineering invited representative researchers from the project, which is supported by the Ministry of Education, Japan.

This volume is a progress report on the project Research and Development of Advanced Database Systems for Integration of Media and User Environments, supported by the Ministry of Education, Science, Sports and Culture of Japan. It investigates research on new database systems due to the recent development of network technology; a clearer picture of integration by database technology is drawn as a result.

This Switzerland-Japan Joint Seminar on Multimedia and Databases was held to achieve at least three goals. First, it enabled us to present and discuss our recent research results and exchange our ideas for further promotion of science and technology. The second goal was to establish a friendly relationship between the Swiss and the Japanese. The last, but not least, aim was to disseminate information about our plans by publishing the proceedings of this seminar. We thought that publishing the outcome of the seminar would be essential in order not to store the treasure — the seminar results — secretly.
