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

Administering the Semantic Web: Confidentiality, Privacy and Trust Management
TL;DR: An approach for ensuring confidentiality, privacy, and trust for the Semantic Web is discussed and the inference and privacy problems within the context of administration policies are discussed.

From Diversity-based Prediction to Better Ontology & Schema Matching
TL;DR: CEM (Match Competitor Deviation), a new diversity-based predictor that compares the strength of a matcher confidence in the correspondence of a concept pair with respect to other correspondences that involve either concept, is proposed.

A Conceptual Schema Language for the Management of Multiple Representations of Geographic Entities
TL;DR: An approach to the modeling of multiple represented entities, which is based on the relationships among the entities and their representations, and central to this approach is the Multiple Representation Schema Language that is used to specify rules that match objects representing the same entity, maintain consistency among these representation, and restore consistency if necessary.

Indexing Based on Object Type
Soren Lassen,Spencer G. Ahrens +1 more
TL;DR: In this article, the authors present a method for maintaining data stores for objects of a social-networking system, each data store being configured to store objects of the particular one of multiple object types indexed by a search index.

Considering Integrity Constraints During Federated Database Design
TL;DR: This paper presents an approach to deal with integrity constraints, which bases on the idea to relate integrity constraints to extensions, and a set of elementary operations for schema restructuring and integration is identified.

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.
