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

Adaptable query optimization and evaluation in temporal middleware
TL;DR: The paper describes the architecture and implementation of the temporal middleware component, termed TANGO, which is based on the Volcano extensible query optimizer and the XXL query processing library, and its cost-based mechanism for apportioning the processing between the middleware and the underlying DBMS.

A healthcare system and user interface for consolidating patient related information from different sources
TL;DR: In this article, a method consolidates patient related information from multiple, different sources by performing the following steps: patient identification data identifying a particular patient is received. Messages are generated for communication to a corresponding information sources.
Journal ArticleDOI
Spatial multi-database topological continuity and indexing: a step towards seamless GIS data interoperability
TL;DR: Structures for spatial indexing in multidatabase systems will be described, giving emphasis to local and global spatial indices, and a r-tree-like-based structure is proposed for organising those global indices.
Journal ArticleDOI
Schema mediation in peer data management systems
TL;DR: This work presents the system — MePSys, which creates a mediated schema in PDMSs automatically using the existing mappings provided to translate queries, and discusses how to update the mediated schemas in a stable state, i.e. after the system setup period.
Patent
Method and apparatus for providing database information to non-requesting clients
TL;DR: In this article, a method and apparatus for providing access to object data stored in a database management system to a receiver client is presented, which comprises the steps of receiving a database query from a submitting client on a first communication path.

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.
