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

A Survey on Data Integration in Bioinformatics
TL;DR: Three techniques for data integration are discussed: the federated database system approach, the data warehousing approach and the link-driven approach.

Integrating Multilevel Security Policies in Multilevel Federated Database Systems
Marta Oliva,Fèlix Saltor +1 more
TL;DR: The proposed methodology includes a way to solve the problem of classification of the components of the Federated Schema generated during the integration process, and obtains the ordered set of classification levels for the multilevel security system of the federation.

Semantics-aware data integration for heterogeneous data sources
TL;DR: The concepts of Semantic Join and Semantic Identifiers are introduced: a declarative approach to semantic data fusion and entity resolution over multiple unrelated databases, which allow to define extremely expressive mapping.

Active object-relational mediators
TL;DR: An active abject-oriented mediator for the enforcement of global consistency between relational legacy databases and how the federated system can be enriched by rule mechanisms that make the mediator behave actively is described.

Enabling Ad Hoc Queries over Low-Level Scientific Data Sets
David Chiu,Gagan Agrawal +1 more
TL;DR: An autonomous scientific workflow system that enables high-level, natural language based, queries over low-level data sets that avoids a standardized format for storing all data sets or the implementation of a federated, mediator-based, querying framework.

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.

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.
