TLDR
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

A framework for building logical schema and query decomposition in data warehouse federations
TL;DR: A framework for building logical schema and query decomposition procedure for federations of data warehouses has been proposed and it is proposed that a user query refers to the schema of the federation, therefore, the query decompose process is needed.

Integrating information for on demand computing
TL;DR: There is still a tremendous amount of research, engineering, and development work needed to make the full information integration vision a reality and it is expected that software companies will continue to heavily invest in aggressively pursing the information Integration vision.

Schemaintegration Integrationskonflikte, Lösungsansätze, aktuelle Herausforderungen
TL;DR: An abstract system architecture for federated database systems as a basis for manifold integration scenarios is introduced and a schema reference architecture is discussed which helps to describe the process of schema integration.

Schema integration of distributed databases using hyper-graph data model
TL;DR: The method developed is based on the hyper-graph data model (HDM) and user's queries are submitted to the integrated schema but executed on local databases via the mapping structure established in the schema integration phase.
Semantics-Based Information Brokering: A Step Towards Realizing the Infocosm
Vipul Kashyap,Amit P. Sheth +1 more
TL;DR: An approach to information brokering in presence of huge digital libraries or millions of information sources will likely require semantics and information-content based search and structuring of information, and an architecture which may facilitate meeting these needs is proposed.

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.
