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

Cost estimation for queries experiencing multiple contention states in dynamic multidatabase environments
TL;DR: Two novel techniques to estimate the cost of a large query that may experience multiple contention states are proposed and demonstrated that the proposed techniques are quite promising in solving the new problem.

Query optimization in multidatabase systems considering schema conflicts
Chiang Lee,Chia-Jung Chen +1 more
TL;DR: This research introduces a new level of query optimization (termed the schema-level optimization) in multidatabase environments and proposes an analytical method that considers the conflicts between local databases and finds the database(s) that renders the least execution cost in processing a global query.

Integration of relational databases in a multidatabase system based on schema enrichment
TL;DR: The authors describe the semantic richment of a relational schema using additional information deduced from its underlying entity-relationship design schema providing the basis for a (semi-)automatic schema transformation.

Informatics and the Human Genome Project
TL;DR: The relationship of informatics to genomic research is considered and the nature of information technology; Moore's Law; informatics as an enabling technology; agency commitments; community recommendations; current trends; and future support are considered.

Book
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.
Book
Fundamentals of Database Systems
TL;DR: Fundamentals of Database Systems combines clear explanations of theory and design, broad coverage of models and real systems, and excellent examples with up-to-date introductions to modern database technologies.
Book
An Introduction to Database Systems

Journal ArticleDOI
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.
