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

Method and apparatus for extending existing database management system for new data types
Felipe Carino,Warren M. Sterling +1 more
TL;DR: In this paper, the authors propose a method and apparatus for extending a relational database management system performed by a computer to manage object data stored in an object server having a processor and a data storage device.

Method and apparatus for managing shared data using a data surrogate and obtaining cost parameters from a data dictionary by evaluating a parse tree object
TL;DR: In this article, the authors propose a method and apparatus for providing access to object data stored in an object server in response to a database query, which comprises the steps of querying a database, transforming the database query into relational database commands, transmitting the database commands to the relational database management system, compiling an answer set from the response table, and transmitting the answer set to the client.

Building National Electronic Medical Record Systems via the World Wide Web
TL;DR: A preliminary EMRS architecture (W3-EMRS) is designed that exploits the multiplatform, multiprotocol, client-server technology of the World Wide Web to enable implementation of programs that provide uniform access to multiple, heterogeneous legacy EMRSs.

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.
