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

Composing Mappings Between Schemas Using a Reference Ontology
Eduard C. Dragut,Ramon Lawrence +1 more
TL;DR: A strategy for computing the mapping between schemas by performing a composition of the mappings between individual schemas and a reference ontology, and is showing how schema-to-ontology matchings can be used to compose mappingsBetween schemas with high accuracy by adapting the COMA schema matching system to work with ontologies.

The design of GSC FieldLog: ontology-based software for computer aided geological field mapping
TL;DR: Benefits of this ontologic-driven approach are also developed within a description of the FieldLog application, including improved usability due to an user interface based on the geological components of the ontology, and diminished technical prerequisites as users are shielded from the many database and GIS technicalities handled by theOntology.

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.
