Abstract :
The AURORA mediator system employs a novel 2-tier, plug-and-play mediation model that is designed to facilitate access to a large number of heterogeneous data sources. The paper describes AURORA´s mediation model and a suite of techniques used by a specific AURORA mediator, AURORA-RH. This suite includes a mediation methodology provided via an interactive mediator author´s toolkit (MAT), a mediation enabling algebra, a query rewriting algorithm, and transformation rules that facilitate query optimization
