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

SchemaSQL: An extension to SQL for multidatabase interoperability
TL;DR: A principled extension of SQL, called SchemaSQL, that offers the capability of uniform manipulation of data and schema in relational multidatabase systems and describes an architecture for the implementation and develops implementation algorithms based on available database technology that allows for powerful integration of SQL based relational DBMS.

ObjectGlobe: Ubiquitous query processing on the Internet
Reinhard Braumandl,Markus Keidl,Alfons Kemper,Donald Kossmann,Alexander Kreutz,Stefan Seltzsam,Konrad Stocker +6 more
TL;DR: The ObjectGlobe security requirements are discussed, how basic components such as the optimizer and runtime system need to be extended are shown, and the results of performance experiments that assess the additional cost for secure distributed query processing are presented.

Contribution of ontology-based data modeling to automatic integration of electronic catalogues within engineering databases
TL;DR: This paper presents an ontology-driven integration approach called a priori approach that ensures the automation of the integration process when all sources reference a shared ontology, and possibly extend it by adding their own concept specializations.
Book
Context Knowledge Representation and Reasoning in the Context Interchange System
TL;DR: The Context Interchange Project presents a unique approach to the problem of semantic conflict resolution among multiple heterogeneous data sources, which presents a semantically meaningful view of the data to the receivers for all the available data sources.

Data manipulation in heterogeneous databases
Abhirup Chatterjee,Arie Segev +1 more
TL;DR: To solve the problem in interdatabase data manipulation within a heterogeneous environment, a broader definition for join operator is proposed and a method to probabilistically estimate the accuracy of the join is discussed.

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.
Book
Fundamentals of Database Systems
TL;DR: Fundamentals of Database Systems combines clear explanations of theory and design, broad coverage of models and real systems, and excellent examples with up-to-date introductions to modern database technologies.
Book

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.
