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

Process Landscaping: Modelling Distributed Processes and Proving Properties of Distributed Process Models
Volker Gruhn,Ursula Wellen +1 more
TL;DR: This work calls a set of hierarchically structured process models, related via interfaces, a process landscape, and develops such a landscape by applying the Process Landscaping method, paying most attention to logical dependencies.

MashUp web data sources and services based on semantic queries
Gilles Nachouki,Mohamed Quafafou +1 more
TL;DR: This paper describes a process for mashing heterogeneous data sources based on the Multi-data source Fusion Approach (MFA) and gives the design of the system MDSManager, which is used to generate the Conflicts data source to improve the problem of rewriting semantic queries into sub-queries over data sources.

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.
