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

Top-down enterprise application integration with reference models
TL;DR: In this article, the authors present a methodology that uses such reference models as a starting point for a top-down integration of enterprise applications, and the actual linking of reference and legacy models is done with a methodology for connecting (new) business objects with (old) legacy systems.

Natural language access to multiple databases: a model and a prototype
Phillip Ein-Dor,Israel Spiegler +1 more
TL;DR: A mechanism for identifying and selecting the appropriate context for a query and its implementation as a prototype are described and the integration of this mechanism into the general model of natural language query processing is indicated and implementational issues are discussed.

Towards a bottom-up development of reference architectures for smart energy systems
TL;DR: The challenges connected with the creation of reference architectures for smart energy systems are illustrated, their benefits are delineated and a model and method for their incremental, bottom-up development and validation through concrete system architectures is suggested.

Cost Modeling and Estimation for OLAP-XML Federations
TL;DR: The cost model has been used as the basis for effective cost-based query optimization in OLAP-XML federations and experiments show that the cost model is precise enough to make a substantial difference in the query optimization process.

RHEEMix in the data jungle: a cost-based optimizer for cross-platform systems
Sebastian Kruse,Zoi Kaoudi,Bertty Contreras-Rojas,Sanjay Chawla,Felix Naumann,Jorge-Arnulfo Quiané-Ruiz +5 more
TL;DR: This paper presents the cost-based optimizer of Rheem, an open-source cross-platform system that copes with new requirements of data analytics and shows that the optimizer can perform tasks more than one order of magnitude faster when using multiple platforms than when using a single platform.

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.
