This book was released on 2007-08-09 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2006 in the subject Computer Science - Applied, grade: 1.0, University of Dusseldorf "Heinrich Heine", language: English, abstract: Federated information systems provide access to interrelated data that is distributed over multiple autonomous and heterogeneous data sources. The integration of these sources demands for flexible and extensible architectures that balance both, the highest possible autonomy and a reasonable degree of information sharing. In current federated information systems, the integrated data sources do only have passive functionality with regard to the federation. However, continuous improvements take the functionality of modern databases beyond former limits. The significant improvement, on which this work is based on, is the ability of modern active database systems to execute programs written in a standalone programming language as user-defined functions or stored procedures from within their database management systems. We introduce Enhanced Active Database Systems as a new subclass of active databases that are able to interact with other components of a federation using external program calls from within triggers. We present several concepts and architectures that are specifically developed for Enhanced Active Databases to improve interoperability and consistency in federated information systems. As the basic concept we describe Active Event Notifications to provide an information system with synchronous and asynchronous update notifications in real-time. Based on this functionality, Enhanced Active Databases are able to actively participate in global integrity maintenance executing partial constraint checks on interrelated remote data. Furthermore, we present an architecture for a universal wrapper component that especially supports Active Event Notifications, which makes it perfectly suitable for event-based federated systems with real-time data processing. This tightly coupled wrapper architecture is used to build up the Dígame architecture for a peer data management system with push-based data and schema replication. Finally, we propose a Link Pattern Catalog as a guideline to model and analyze P2P-based information systems.

Available in PDF, EPUB and Kindle. Book excerpt: As the information contained in databases has become a critical resource in organizations, efficient access to that information and the ability to share it among different users and across different systems has become an urgent need. The interoperability of heterogeneous database systems-literally, the ability to access information between or among differing types of databases, is the topic of this timely book. In the last two decades, tremendous improvements in tools and technologies have resulted in new products that provide distributed data processing capabilities. This book describes these tools and emerging technologies, explaining the essential concepts behind the topics but focusing on practical applications. Selected products are discussed to illustrate the characteristics of the different technologies. This is an ideal source for anyone who needs a broad perspective on heterogeneous database integration and related technologies.

This book was released on 2013-06-29 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Helene Bestougeff, Universite de Marne Ia Vallee, France Jacques-Emile Dubois, Universite Paris VII-Denis Diderot, France Bhavani Thuraisingham, MITRE Corporation, USA The last fifty years promoted the conceptual trio: Knowledge, Information and Data (KID) to the center of our present scientific technological and human activities. The intrusion of the Internet drastically modified the historical cycles of communication between authors, providers and users. Today, information is often the result of the interaction between data and the knowledge based on their comprehension, interpretation and prediction. Nowadays important goals involve the exchange of heterogeneous information, as many real life and even specific scientific and technological problems are all interdisciplinary by nature. For a specific project, this signifies extracting information, data and even knowledge from many different sources that must be addressed by interoperable programs. Another important challenge is that of corporations collaborating with each other and forming coalitions and partnerships. One development towards achieving this challenge is organizational hubs. This concept is new and still evolving. Much like an airport hub serving air traffic needs, organizational hubs are central platforms that provide information and collaboration specific to a group of users' needs. Now companies are creating hubs particular to certain types of industries. The users of hubs are seen as communities for which all related information is directly available without further searching efforts and often with value-added services.
