Book excerpt: Abstract: "When a database is shared by many users, updates to the database schema are almost always prohibited because there is a risk of making existing application programs obsolete when they run against the modified schema. This paper addresses the problem by integrating schema evolution with view facilities. Each user is assigned his or her own database view, and develops application programs against the view. When new requirements necessitate schema updates for a particular user, then the user specifies schema changes to his personal view rather than to the shared base schema. Our view schema evolution approach then computes a new view schema that reflects the semantics of the desired schema change, and replaces the old view with the new one. This approach provides the means for schema change without affecting other views (and thus without affecting existing application programs). The persistent data is shared by different views of the schema, i.e. by both old as well as newly developed applications can continue to interoperate. To realize our approach, this paper identifies key features of how views must be extended to be capacity- augmenting. We then present algorithms that implement the set of typical schema evolution operations as view definitions. Throughout the paper we present examples that demonstrate our approach."

Book excerpt: The Ninth International Workshop on Foundations of Models and Languages for Data and Objects (FoMLaDO) took place in Dagstuhl Germany, Sept- ber 18{21, 2000. The topic of this workshop was Database schema Evolution and Meta-Modeling; this FoMLaDO Workshop was hence assigned the acronym DEMM 2000. These post-proceedings contain the revised versions of the accepted papers of the DEMM 2000 workshop. Twelve regular papers were accepted for inclusion in the proceedings. The papers address the following issues: { Consistency of evolving concurrent information systems { Adaptive speci cations of technical information systems { Change propagation in schema evolution of object-based systems { Evolving software of a schema evolution system { Logical characterization of schema evolution { Con?ict management in integrated databases { Evolving relation schemas { Conceptual descriptions of adaptive information systems { OQL-extensions for metadata access { Metamodeling of schema evolution { Metrics for conceptual schema evolution { Incremental datawarehouse construction In addition to the regular papers, there is an invited paper by Can Turk ̈ er on schema evolution in SQL99 and (object-)relational databases.

Available in PDF, EPUB and Kindle. Book excerpt: The Sorbonne University is very proud to host this year the oms Conference on Object Oriented Information Systems. There is a growing awareness of the importance of object oriented techniques, methods and tools to support information systems engineering. The term information systems implies that the computer based systems are designed to provide adequate and timely information to human users in organizations. The term engineering implies the application of a rigorous set of problem solving approaches analogous to those found in traditional engineering disciplines. The intent of this conference is to present a selected number of those approaches which favor an object oriented view of systems engineering. oms '98 is the fifth edition of a series of conferences. Starting in 1994 in London, this series evolved from a British audience to a truly European one. The goal is to build a world wide acknowledged forum dedicated to object oriented information systems engineering. This conference is organized with the aim to bring together researchers and practitioners in Information Systems, Databases and Software Engineering who have interests in object oriented information systems. The objective is to advance understanding about how the object technology can empower information systems in organizations, on techniques for designing effective and efficient information systems and methods and development tools for information systems engineering. The conference aims also at discussing the lessons learned from large scale projects using objects. The call for oms was given international audience.

Book excerpt: This volume contains the proceedings of the Second International Conference on Advances in Information Systems (ADVIS) held in Izmir, Turkey, 23–25 October 2002. This conference was dedicated to the memory of Prof. Esen Ozkarahan. He was a great researcher who made an essential contribution to the development of information systems. Prof. Ozkarahan was one of the pioneers of database machine research and database systems in Turkey. This conference was organized by the Computer Engineering department of Dokuz Eylul University in Izmir. This department was established in 1994 by Prof. Ozkarahan and he worked there for the last ?ve years of his life. The main goal of the conference was to bring together researchers from all around the world working in di?erent areas of information systems, to share new ideas and present their latest results. This time we received 94 submissions from 27 countries. The program committee selected 40 papers for presentation at the conference. During the conference a workshop was organized on the topic “New Information Technologies in Education”. The invited and accepted cont- butions cover a large variety of topics: general aspects of information systems, databases and data warehouses, information retrieval, multiagent systems and technologies, distributed and parallel computing, evolutionary algorithms and system programming, and new information technologies in education. The success of the conference was dependent upon the hard work of a large number of people. We gratefully acknowledge the members of the Program C- mittee who helped to coordinate the process of refereeing all submitted papers.

Available in PDF, EPUB and Kindle. Book excerpt: The database field has experienced a rapid and incessant growth since the development of relational databases. The progress in database systems and applications has produced a diverse landscape of specialized technology areas that have often become the exclusive domain of research specialists. Examples include active databases, temporal databases, object-oriented databases, deductive databases, imprecise reasoning and queries, and multimedia information systems. This book provides a systematic introduction to and an in-depth treatment of these advanced database areas. It supplies practitioners and researchers with authoritative coverage of recent technological advances that are shaping the future of commercial database systems and intelligent information systems. Advanced Database Systems was written by a team of six leading specialists who have made significant contributions to the development of the technology areas covered in the book. Benefiting from the authors' long experience teaching graduate and professional courses, this book is designed to provide a gradual introduction to advanced research topics and includes many examples and exercises to support its use for individual study, desk reference, and graduate classroom teaching.
