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

Integrating ontologies and thesauri for RDF schema creation and metadata querying
TL;DR: A fairly simple database-oriented solution for querying application-specific metadata which avoids a (recursive) tree traversal and is based on a linear encoding of thesaurus hierarchies.

Are we moving toward an information superhighway or a Tower of Babel? The challenge of large-scale semantic heterogeneity
TL;DR: Various forms of context challenges and examples of potential context mediation services, such as data semantics acquisition, data quality attributes and evolving semantics and quality, that can mitigate the problem are described.

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.
