Databases and Information Systems II : Fifth International Baltic Conference, Baltic DB & IS'2002 Tallinn, Estonia, June 3-6, 2002 Selected Papers

Databases and database systems in particular, are considered as kerneIs of any Information System (IS). The rapid growth of the web on the Internet has dramatically increased the use of semi-structured data and the need to store and retrieve such data in a database. The database community quickly reacted to these new requirements by providing models for semi-structured data and by integrating database research to XML web services and mobile computing. On the other hand, IS community who never than before faces problems of IS development is seeking for new approaches to IS design. Ontology­ based approaches are gaining popularity, because of a need for shared conceptualisation by different stakeholders of IS development teams. Many web-based IS would fail without domain ontologies to capture meaning of terms in their web interfaces. This volume contains revised versions of 24 best papers presented at the th 5 International Baltic Conference on Databases and Information Systems (BalticDB&IS'2002). The conference papers present original research results in the novel fields of IS and databases such as web IS, XML and databases, data mining and knowledge management, mobile agents and databases, and UML based IS development methodologies. The book's intended readers are researchers and practitioners who are interested in advanced topics on databases and IS.

The rapid growth of the Internet has dramatically changed the capabilities of information systems (IS) and the role of database management. They have become vital components of successful inter-networked enterprises and organizations. This volume considers fundamental issues and technical development in the integrated section of the fields of databases and modern IS.

The book contains a collection of 24 high quality papers written by 56 authors. These articles present original results that constitute a survey of both the research and technological dimensions related to the modern IS and database development. The database research emphasises distributed databases, XML and databases, mobile agents and databases, data mining and knowledge management. The IS development issues include ontology-based and knowledge-based approaches to systems development, UML based IS development methodologies, and web IS. These papers are of particular interest to researchers, developers, advanced students, and practitioners who are concerned with the development of modern IS.
