In this paper, the authors define a reference architecture for distributed database management systems from system and schema viewpoints and show how various FDBS architectures can be developed, and define a methodology for developing one of the popular architectures of an FDBS.Abstract:
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

An Experiment in Integrating Large Biomedical Knowledge Resources with RDF: Application to Associating Genotype and Phenotype Information
TL;DR: This paper demonstrates how the Resource Description Framework (RDF) can be used to represent and integrate these resources and support complex queries over the unified resource, and illustrates the effectiveness by answering a real-world biomedical query linking a specific molecular function, glycosyltransferase, to the disorder congenital muscular dystrophy.

Diversity with Cooperation in Database Schemata: Semantic Relativism.
TL;DR: This work first analyzes diversity within an information system, where cooperation is made possible by the use of external schemata; semantic relativism of the model of the database schema is the key f,ictor.

Joins for Hybrid Warehouses: Exploiting Massive Parallelism in Hadoop and Enterprise Data Warehouses
TL;DR: It is shown that it is actually better to do most data processing on the HDFS side, provided that it can leverage a sophisticated execution engine for joins on the Hadoop side, and a new zigzag join algorithm is described that is a robust join algorithm for hybrid warehouses which performs well in almost all cases.

Virtual integration of sensor observation data
TL;DR: This paper discusses the design, implementation and evaluation of a framework that enables the virtual integration of heterogeneous observation data sources through a Sensor Observation Service (SOS) standard interface, using a well-known Mediator/Wrapper virtual data integration architecture.

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.
