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

Large Multidatabases: Issues and Directions
Athman Bouguettaya,Roger King +1 more
TL;DR: The size of the multidatabase system is the single most important criterion that shapes the complexity of the problem and as the size becomes larger, new problems related to database autonomy and heterogeneity, as well as user education about available information, surface.

Access Control for Data Integration in Presence of Data Dependencies
TL;DR: This paper uses a graph-based approach to identify sets of queries, called violating transactions, and proposes an approach to forbid the execution of those transactions by identifying additional access control rules that should be added to the mediator.

Executing multidatabase transactions
TL;DR: One of such extensions, the flexible transaction model, is described, the scheduling of transactions involving multiple autonomous database systems managed by heterogeneous DBMS is discussed and the scheduling algorithm for flexible transactions is implemented using L.0.

A service-oriented system for distributed data querying and integration on Grids
TL;DR: The implementation of a data sharing system that is tailored to data Grids, supports well established and widely spread relational DBMSs, and adopts a hybrid architecture by relying on a peer model for query reformulation to retrieve semantically equivalent expressions is presented.

Entity matching in heterogeneous databases: A logistic regression approach
TL;DR: This paper proposes an alternative technique based on logistic regression for estimating the matching probabilities to be used in the matching decision model and indicates that the proposed approach performs quite well and is certainly a viable approach in practical situations.

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.
