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

Composing mappings among data sources
Jayant Madhavan,Alon Halevy +1 more
TL;DR: This paper investigates the theoretical underpinnings of mapping composition for a rich mapping language, GLAV, and shows that for a commonly occuring class of queries it is possible to pre-compose mappings, thereby potentially offering significant savings in query processing.

Data model and query evaluation in global information systems
TL;DR: An architecture for global information systems that is especially tailored to address the challenges raised in such an environment is described, and the need for interleaving planning and query execution in such a system is demonstrated.

Resource integration using a large knowledge base in Carnot
TL;DR: The method provides logical connectivity among the information resources via a semantic service layer that automates the maintenance of data integrity and provides an approximation of global data integration across systems.

Description logic framework for information integration
TL;DR: This work presents a novel approach to conceptual modeling for Information Integration, which allows for suitably modeling the global concepts of the application, the individual information sources, and the constraints among different sources.

An interactive clustering-based approach to integrating source query interfaces on the deep Web
TL;DR: An interactive, clustering-based approach to matching query interfaces, which puts the human integrator back in the loop and proposes several novel approaches to the interactive learning of parameters and the resolution of uncertain mappings.

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.

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.
