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

Management of uncertain data : towards unattended integration
TL;DR: A new data model, based on XML that is capable of storing uncertainty about elements and subtrees is presented and knowledge rules that help deciding on equality during the integration phase are introduced, so that integrated documents contain less uncertainty and are therefore smaller in size.

Converting XML DTDs to UML diagrams for conceptual data integration
TL;DR: Algorithms for automatically constructing UML diagrams from XML DTDs are presented, enabling fast and easy graphical browsing of XML data sources on the web, and an integration architecture is presented.
A Classification of Schema Mappings and Analysis of Mapping Tools
Frank Legler,Felix Naumann +1 more
TL;DR: No tool performs well in all mapping situations and that many tools pro- duce incorrect data transformations, so a general suite of schemata, data, and correspondences can serve as a benchmark for future improvements and developments of schema mapping tools.

Sushil K. Prasad,Anu G. Bourgeois,Erdogan Dogdu,Rajshekhar Sunderraman,Yi Pan,Shamkant B. Navathe,Vijay K. Madisetti +6 more
TL;DR: System of Mobile Devices is a middleware that can be used for implementing collaborative, mobile, and distributed applications over heterogeneous devices, data stores, and computing environments and SyDLink objects provide the underlying mechanism in SyD to enforce atomic execution of distributed transactions.

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.
