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

Uncertain Schema Matching
TL;DR: Various aspects of uncertainty in schema matching within a single unified framework are presented and basic formulations of uncertainty are introduced and several alternative representations of schema matching uncertainty are provided.

An Information Model Based on Classification Theory
TL;DR: This paper develops a formal information structuring model based on the premise that an information system represents knowledge about things in an organization which emphasizes instances and properties, rather than fixed categories of data or schemas.

Information integration in schema-based peer-to-peer networks
TL;DR: The concept of super-peer networks which provide better scalability compared to traditional P2P networks are shown which are able to support sophisticated routing, clustering and mediation strategies based on the metadata schemas and attributes.

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.
