This book was released on 2010 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Database transformations consist of queries and updates which are two fundamental types of computations in any databases - the first provides the capability to retrieve data and the second is used to maintain databases in light of ever-changing application domains. This dissertation aims to lay down the foundations for establishing a theoretical framework of database transformations in the context of complex-value databases. The previous findings reveal that it is very difficult to characterise common features of database queries and updates in a way which is meaningful for further investigations. Nevertheless, the advent of the sequential Abstract State Machine (ASM) thesis capturing sequential algorithms sheds light on the study of database transformations. Observing that the class of computations described by database transformations may be formalised as algorithms respecting database principles, we propose the database ASM thesis for a complete characterisation of database transformations. It turns out that every database transformation characterised by five postulates can be behaviourally simulated by a database Abstract State Machine (DB-ASM) with the same signature and background, and vice versa. Furthermore, a logic for DB-ASMs is defined. In spite of bounded non-determinism permitted by DB-ASMs, the logic is proven to be sound and complete.

This book was released on 1997-05-28 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Sobolev gradient of a real-valued functional is a gradient of that functional taken relative to the underlying Sobolev norm. This book shows how descent methods using such gradients allow a unified treatment of a wide variety of problems in differential equations. Equal emphasis is placed on numerical and theoretical matters. Several concrete applications are made to illustrate the method. These applications include (1) Ginzburg-Landau functionals of superconductivity, (2) problems of transonic flow in which type depends locally on nonlinearities, and (3) minimal surface problems. Sobolev gradient constructions rely on a study of orthogonal projections onto graphs of closed densely defined linear transformations from one Hilbert space to another. These developments use work of Weyl, von Neumann and Beurling.

Download or read book Logical Database Design Principles written by John Garmany and published by CRC Press. This book was released on 2005-05-12 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now, almost all books on logical database design focused exclusively on relational design. However, modern database management systems have added powerful features that have driven a movement away from truly normalized database design. Logical Database Design Principles reflects these recent changes. The book begins by covering traditional logical design principles, followed by an analysis of the normalizing and modeling of data. It then examines designing for specific purposes, such as object-oriented databases, online transaction processing (OLTP), and data warehouses. As the text progresses, it moves from the purely logical into some physical design, as determined by how the features of modern databases are implemented. Because this is a logical-design book, the authors attempt to make the examples database-neutral. Because various vendors implement features in different ways, this volume sometimes offers examples from a specific database management system. When necessary, it highlights a specific application, clearly demonstrating the concept being discussed.

Download or read book Modelling Database Dynamics written by Udo W. Lipeck and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Database modelling is concerned with the design of reliable and efficient database systems. Three different approaches to modelling can be identified: structure-oriented, process-oriented, and behaviour-oriented. Database literature has traditionally focused on structure-oriented approaches, but it is now widely recognised that problems can be solved more effectively by integrating all three. As a result, modelling database dynamics is now considered to be as important as modelling static database structures. This volume contains selected papers from the Fourth International Workshop on Foundations of Models and Languages for Data and Objects, held in Volkse, Germany, 19-22 October, 1992. This series of international workshops was initiated by the Working Group on Foundations of Information Systems, part of the German Association for Informatics. It provides an international forum for the discussion of current research into database theory and its application to database technology. The theme of this particular workshop was modelling the dynamic behaviour of database systems in formal frameworks. As object-oriented principles are being widely used in current research work, particular emphasis was also given to object dynamics. Among the topics covered in this volume are: specifying the dynamics of complex objects databases; updates in a rule-based language for objects; an order-sorted approach to active objects; non-deterministic aspects of database transformations involving object creation; monitoring temporal permissions using partially evaluated transition graphs; a formalisation of logic databases and integrity constraints; a comparison of approaches for modelling dynamics of databases. Modelling Database Dynamics provides a comprehensive overview of current research into the modelling and use of database dynamics. It will provide invaluable reading for researchers, postgraduate students, and anyone interested in the theoretical foundations of computer science.
Download or read book Fundamentals of Software Integration written by Kay Hammer and published by Jones & Bartlett Learning. This book was released on 2008 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integration is one of the most critical technical challenges in software today, as well as a difficult topic to generalize because of the many things affecting it — the technologies involved, the timeframe, the number and types of user communities requiring access, regulatory requirements, and so on. For this reason, Hammer and Timmerman have developed this comprehensive and unique overview of the evolution of software technology, with a particular emphasis on long-standing problems that remain unsolved. Fundamentals of Software Integration builds on this through background, presenting an abstract model of the software application and its environment, along with a methodology for how to use this model to develop an integration strategy that meets both the short– and long–term needs of an organization. This text utilizes an accessible writing style and strategic exercises to help students recognize similarities in the integration challenges faced across technologies.
Download or read book Information Modelling and Knowledge Bases XXIX written by V. Sornlertlamvanich and published by IOS Press. This book was released on 2018-02-09 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information modelling and knowledge bases have become ever more essential in recent years because of the need to handle and process the vast amounts of data which now form part of everyday life. The machine to machine communication of the Internet of Things (IoT), in particular, can generate unexpectedly large amounts of raw data. This book presents the proceedings of the 27th International Conference on Information Modelling and Knowledge Bases (EJC2017), held in Krabi, Thailand, in June 2017. The EJC conferences originally began in 1982 as a co-operative initiative between Japan and Finland, but have since become a world-wide research forum bringing together researchers and practitioners in information modelling and knowledge bases for the exchange of scientific results and achievements. Of the 42 papers submitted, 29 were selected for publication here, and these cover a wide range of information-modelling topics, including the theory of concepts, semantic computing, data mining, context-based information retrieval, ontological technology, image databases, temporal and spatial databases, document data management, software engineering, cross-cultural computing, environmental analysis, social networks, and WWW information. The book will be of interest to all those whose work involves dealing with large amounts of data.
