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

Intranet Meets Hospital Information Systems: The Solution to the Integration Problem?
Richard Lenz,Klaus A. Kuhn +1 more
TL;DR: This paper summarizes the state of the art in web technology and compares it with the needs of integration in hospital information systems and finds a common ontological basis for future component based systems.
The Role of Ontology in Integrating Semantically Heterogeneous Databases
TL;DR: In this article, the authors describe how ontology can contribute to delivering a more efficient and effective process of matching by providing a framework for the analysis, and so the basis for a methodology.

Reformulating query plans for multidatabase systems
Chun-Nan Hsu,Craig A. Knoblock +1 more
TL;DR: This paper presents an automated approach to reformulating query plans to improve the efficiency of multidatabase queries, using database abstractions, the knowledge about the contents of databases, to reformulate a query plan into a less expensive but semantically equivalent one.

Semantic heterogeneity in distributed geographic databases
M. F. Worboys,S. M. Deen +1 more
TL;DR: This paper considers the special problems of semantic heterogeneity in a distributed system of databases containing spatially referenced information and proposes two possible solutions using a canonical model which is a generalization of existing generic spatial models.

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.
