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.
