Available in PDF, EPUB and Kindle. Book excerpt: In a database design process the database model used is essential for producing a good conceptual schema. In most database models, like IMS and CODASYL, a conceptual schema contains too many implementation details which complicate the designer's task. The conceptual schema of a relational database hides too much information from the user, because it lacks the necessary structure. The standard E-R model has more structure and is easy to use. But, it still lacks the ability to express certain types of abstract concepts needed in most design processes. In this work an extended E-R model is used, which includes abstraction hierarchies. A conceptual schema language (EXERM-CSL), extended in order to include abstraction hierarchies, is proposed to define the structural part of the model. The integrity part of the model has also been included. No model would be complete without the manipulative part. Many languages have been proposed for the E-R model. Some of them take advantage of a schema graph, as for instance GORDAS. Others are based on the concept of simplified completeness, like Executable Language for instance. In this work we propose a high-level query language (EXERM-DML), which not only makes use of the E-R diagram, but it is also based on the Reshaped Relational Algebra (RRA), which gives more expressive power to the language itself. EXERM-DML also makes provisions for abstraction hierarchies. Finally EXERM-DML is a complete database language as far as retrieval, insertion, and updating of data is concerned.

Available in PDF, EPUB and Kindle. Book excerpt: The growing demand for systems of ever-increasing complexity and precision has stimulated the need for higher level concepts, tools, and techniques in every area of Computer Science. Some of these areas, in particular Artificial Intelligence, Databases, and Programming Lan guages, are attempting to meet this demand by defining a new, more abstract level of system description. We call this new level conceptual in recognition of its basic conceptual nature. In Artificial Intelligence, the problem of designing an expert system is seen primarily as a problem of building a knowledge base that repre sents knowledge about an enterprise. Consequently, Knowledge Repre sentation is viewed as a central issue in Artificial Intelligence research. Database design methodologies developed during the last five years are almost unanimous in offering semantic data models in terms of which the designer directly and naturally models an enterprise before proceed ing to a detailed logical and physical database design. In Programming Languages, different forms of abstraction which allow implementation independent specifications of data, functions, and control have been a major research theme for a decade. To emphasize the common goals of these three research efforts, we call this new activity conceptual modelling.

Available in PDF, EPUB and Kindle. Book excerpt: Information Modeling and Relational Databases, Third Edition, provides an introduction to ORM (Object-Role Modeling) and much more. In fact, it is the only book to go beyond introductory coverage and provide all of the in-depth instruction you need to transform knowledge from domain experts into a sound database design. This book is intended for anyone with a stake in the accuracy and efficacy of databases: systems analysts, information modelers, database designers and administrators, and programmers. Dr. Terry Halpin and Dr. Tony Morgan, pioneers in the development of ORM, blend conceptual information with practical instruction that will let you begin using ORM effectively as soon as possible. The all-new Third Edition includes coverage of advances and improvements in ORM and UML, nominalization, relational mapping, SQL, XML, data interchange, NoSQL databases, ontological modeling, and post-relational databases. Supported by examples, exercises, and useful background information, the authors’ step-by-step approach teaches you to develop a natural-language-based ORM model, and then, where needed, abstract ER and UML models from it. This book will quickly make you proficient in the modeling technique that is proving vital to the development of accurate and efficient databases that best meet real business objectives. "This book is an excellent introduction to both information modeling in ORM and relational databases. The book is very clearly written in a step-by-step manner and contains an abundance of well-chosen examples illuminating practice and theory in information modeling. I strongly recommend this book to anyone interested in conceptual modeling and databases." — Dr. Herman Balsters, Director of the Faculty of Industrial Engineering, University of Groningen, The Netherlands Presents the most in-depth coverage of object-role modeling, including a thorough update of the book for the latest versions of ORM, ER, UML, OWL, and BPMN modeling. Includes clear coverage of relational database concepts as well as the latest developments in SQL, XML, information modeling, data exchange, and schema transformation. Case studies and a large number of class-tested exercises are provided for many topics. Includes all-new chapters on data file formats and NoSQL databases.

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. Acknowledgements: We wish to thank the program committee members for their work on reviewing the submitted papers. We also wish to thank all a- hors for submitting papers to this workshop. Moreover, all participants of the workshop are thanked for contributing to lively discussions. Thanks also to Elke Rundensteiner, who delivered an invited talk on the SERF-project concerning ?exible database transformations.

Design methods, specification languages, and tools tend to become application dependent, aiming at integration of methodologies stretching traditional database design to advanced knowledge bases, and including use of logical languages, and process oriented system description. The topics of the articles in this book cover a wide variety of themes in the domain of information modelling, specifications of information systems and knowledge bases, ranging from foundations and theories to systems construction and application studies. The contributions represent the following major themes: the use of ontologies in knowledge modelling concept modelling and conceptual modelling database modelling: applications of object-oriented modelling view integration and consistency checking modelling multimedia and multimedia models design methods process modelling formal systems.
