Modern databases and information systems essentially differ from their predecessors. Ontology-based and knowledge-based approaches to system development, UML based IS development methodologies, XML databases and heterogeneous information models have come to the fore. All these fundamental aspects are discussed in this book. This publication contains a collection of 22 high quality papers written by 44 authors. These articles present original results in modern database technologies, database applications, data warehousing, data mining, ontologies, and modern information systems. Special emphasis is put on multimedia database systems, heterogeneous data integration methods, view optimizations, ontology engineering tools, modeling and model transformations (MDA). Theoretical aspects as well as technical development issues are considered. The intended audience for this book is researchers, advanced students and practitioners who are interested in advanced topics on databases and information systems.

Modern information systems differ in essence from their predecessors. They support operations at multiple locations and different time zones, are distributed and network-based, and use multidimensional data analysis, data warehousing, knowledge discovery, knowledge management, mobile computing, and other modern information processing methods. This book considers fundamental issues of modern information systems. It discusses query processing, data quality, data mining, knowledge management, mobile computing, software engineering for information systems construction, and other topics. The book presents research results that are not available elsewhere. With more than 40 contributors, it is a solid source of information about the state of the art in the field of databases and information systems. It is intended for researchers, advanced students, and practitioners who are concerned with the development of advanced information systems.

This volume presents a substantial part of the results obtained in the last few years in the field of computer science in the Baltic Republics of Estonia, Latvia and Lithuania. It includes results previously published only in Russian as well as completely new results. The following main topics are addressed: deductive synthesis of programs, automatic test case generation, and specification and generation of distributed systems. These are all fields where Baltic scientists have made substantial contributions. The volume contains both theoretical results and general descriptions and logical outlines of some practical systems.
