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

Decoupled query optimization for federated database systems
TL;DR: The design space for a query optimizer in this federated relational database environment is explored, the need for decoupling various aspects of the optimization process is demonstrated, and minimum-communication decoupled variants of various query optimization techniques are presented.

Generalized optimal wavelet decomposing algorithm for big financial data
TL;DR: A new wavelet-based methodology is proposed (named GOWDA, i.e., the generalized optimal wavelet decomposition algorithm) that allows to deconstruct price series into the true efficient price and microstructure noise, particularly for the noise that induces the phase transition behaviors.

Information infrastructure
TL;DR: The authors assert that the most pressing information-infrastructure requirement now facing the HGP is achieving better interoperation among electronic information resources.

Distributed databases and peer-to-peer databases: past and present
TL;DR: By distinguishing between db-centric and P2P-centric features, this paper examines features common to these database systems as well as other ad-hoc features that solely characterize P2p databases and provides a non-exhaustive taxonomy of the most prominent research efforts toward the realization of full-fledged P1P databases.

AMOS - An Architecture for Active Mediators
TL;DR: A distributed AMOS architecture is being developed where several AMOS servers communicate, and where queries in a multi-database language are allowed to refer to several AMos databases or other data sources.

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
An Introduction to Database Systems
TL;DR: Readers of this book will gain a strong working knowledge of the overall structure, concepts, and objectives of database systems and will become familiar with the theoretical principles underlying the construction of such systems.

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.
