In this paper, the authors define a reference architecture for distributed database management systems from system and schema viewpoints and show how various FDBS architectures can be developed, and define a methodology for developing one of the popular architectures of an FDBS.Abstract:
A federated database system (FDBS) is a collection of cooperating database systems that are autonomous and possibly heterogeneous. In this paper, we define a reference architecture for distributed database management systems from system and schema viewpoints and show how various FDBS architectures can be developed. We then define a methodology for developing one of the popular architectures of an FDBS. Finally, we discuss critical issues related to developing and operating an FDBS.read more

Object-extended OLAP querying
TL;DR: A prototype implementation of the flexible, ''multi-model'' federated system that enables OLAP users to exploit simultaneously the features of OLAP and object systems is reported, along with performance measurements that show that the approach is a viable alternative to a physically integrated data warehouse.
Journal ArticleDOI
Interoperability in information systems
TL;DR: It is demonstrated that preservation of strong design autonomy is not always possible owing to necessity to resolve semantic hereogeneity among the systems, which calls into question the utility of research on general a tectures and the possibility of general solutions.

A Linked Data approach for the discovery of educational ICT tools in the Web of Data
Adolfo Ruiz-Calleja,Guillermo Vega-Gorgojo,Juan I. Asensio-Pérez,Miguel L. Bote-Lorenzo,Eduardo Gómez-Sánchez,Carlos Alario-Hoyos +5 more
TL;DR: Evaluation results show that available information on the Web of Data can be used to obtain suitable tools for real educational settings, thus overcoming the sustainability problems of existing ICT tool registries.
Journal ArticleDOI
A data‐mining approach for assessing consistency between multiple representations in spatial databases
TL;DR: This paper proposes a knowledge‐based approach to partially automate the consistency assessment between multiple representations of data, and proposes a supervised learning approach to automate the knowledge acquisition so as to drastically reduce the human‐domain expert's work.
Proceedings ArticleDOI
Detection of heterogeneities in a multiple text database environment
TL;DR: This work first analyzes the impact of various heterogeneities on building a metasearch engine, then presents some techniques that can be used to detect the most prominentheterogeneities among multiple search engines.

The entity-relationship model: toward a unified view of data
TL;DR: A data model, called the entity-relationship model, is proposed that incorporates some of the important semantic information about the real world and can be used as a basis for unification of different views of data: the network model, the relational model, and the entity set model.
Book
Fundamentals of Database Systems
TL;DR: Fundamentals of Database Systems combines clear explanations of theory and design, broad coverage of models and real systems, and excellent examples with up-to-date introductions to modern database technologies.
Book
An Introduction to Database Systems
TL;DR: Readers of this book will gain a strong working knowledge of the overall structure, concepts, and objectives of database systems and will become familiar with the theoretical principles underlying the construction of such systems.

Journal ArticleDOI
A comparative analysis of methodologies for database schema integration
TL;DR: The aim of the paper is to provide first a unifying framework for the problem of schema integration, then a comparative review of the work done thus far in this area, providing a basis for identifying strengths and weaknesses of individual methodologies, as well as general guidelines for future improvements and extensions.
