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

Method and apparatus for providing shared data to a requesting client
TL;DR: In this article, a method and apparatus for providing object data stored in a database management system to a receiving client is presented, which comprises the steps of receiving a database query from the client on a first communication path, transforming the database query into database manager's commands, transmitting the database management management system commands to the database manager, receiving a response from the DBMS, the response comprising an object locator identifying data responsive to the query, compiling an answer set comprising the database managers' response, and transmitting the answer set to the client, and establishing a transport session with the client
Patent
Ultra-shared-nothing parallel database
TL;DR: An ultra-shared-nothing parallel database system includes at least one master node and multiple slave nodes as mentioned in this paper, where the fact table and the first dimension table of the database are partionned across the slave nodes.
Patent
Method and apparatus for parallel execution of user-defined functions in an object-relational database management system
TL;DR: In this paper, a federated coordinator coupled to the client interface for translating client commands into object server commands, an object server coupled with a processor and a data storage device for storing the object data, a virtual processor instance, invoked on the processor for performing the data function on the data identified by the data surrogate to produce processed data, and a virtual disk instance invoked in the data storage devices and logically associated with the virtual processor instances for storing object data.

Delivering the electronic healthcare record for the 21st century.
TL;DR: This paper discusses some of the key impediments to progress including in particular, the lack of application of software engineering methodologies, the absence of usable standards, and the failure to acknowledge the impact of record systems on the healthcare system itself.

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.
