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

Cross-chain Deals and Adversarial Commerce.
TL;DR: In this paper, the authors propose the notion of cross-chain deals, a new way to structure complex distributed computations that manage assets in an adversarial setting, inspired by classical atomic transactions, but are necessarily different in important ways to accommodate the decentralized and untrusting nature of the exchange.

A Change Impact Analysis Approach for CORBA-Based Federated Databases
Laurent Deruelle,Mourad Bouneffa,Nouredine Melab,Henri Basson,Gilles Goncalves,Jean-Christophe Nicolas +5 more
TL;DR: An approach and a framework for an a priori change impact analysis of database schemas, in federated environment, based on a model, that takes into account the software components for both centralized and CORBA-based federated database applications is proposed.

Exploring standardization and integration in the implementation of industry inter-organizational information systems: a case study in the seaport of Barcelona
Abstract: The proliferation of applications to support cross-enterprise processes has left companies nursing a collection of systems The integration of such systems, within and across the organizational boundaries, remains a top issue of researchers and practitioners’ agendas Although integration has long been treated as a key variable in the IS field, the construct has received little conceptual scrutiny In this essay we argue that the concept of IOIS integration (cross-enterprise integration of information systems) is still ambiguous and lacks an understanding on its nature Thus we explore prior literature that has attempted to conceptualize IOIS integration We examine dimensions that concern both the methodology used (epistemology, theoretical perspective, research approach, duration of the study, conceptual model and unit of analysis), and the construct (scope, layer of integration Exploring Standardization and Integration in the Implementation of Industry Inter-Organizational Information Systems: A Case Study in the Seaport of Barcelona Research Findings 48 and conceptualization of the ICT artifact) Sixty-one articles are reviewed We present the results and discuss different dimensions of the construct (definition, antecedents, consequences and measures) The purpose of this literature survey is to shed some light on the IOIS integration construct as well as to uncover areas for future research 412 Paper 2: “The Dynamics of an IOIS in the Seaport of Barcelona: An ANT Perspective”

Multidimensional service-oriented ontology mapping
Nuno Silva,João Rocha +1 more
TL;DR: The main contributions of this paper are the formalisation of the ontology mapping process and the specification of the multidimensional service-oriented architecture.
On schema and functional architectures for multilevel secure and multiuser model federated DB systems
TL;DR: An approach for tightly federated database systems with several federated schemas that consists of a schema architecture and a functional architecture to deal with security aspects not well solved previously is presented.

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.
