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

General Strategy for Querying Web Sources in a Data Federation Environment
TL;DR: This strategy separates the code and knowledge in wrapper development by introducing a general-purpose capabilities-aware mini query-planner and a data extraction engine so that Web sources can be included in a data federation system faster, and maintained easier.

Engineering data management: achieving integration through database technology
TL;DR: An architecture is given for engineering data management that incorporates current work on engineering product standards as well as current work in database research, and a framework that views an engineering design environment as an integrated, heterogeneous database system is presented.
Book ChapterDOI
Secure Mediation: Requirements and Design
TL;DR: The basic approach suitably combines the concepts of credentials, for authentic authorization with some kind of anonymity, and of asymmetric encryption, for confidentiality, and it can be extended to include additional mechanisms like digital signatures and fingerprints.

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.
