摘要

AURORA中介系统采用一种新颖的两层即插即用中介模型，该模型旨在促进对大量异构数据源的访问。本文描述了AURORA的中介模型和一套由特定的AURORA中介使用的技术，AURORA- rh。该套件包括通过交互式中介作者工具包(MAT)提供的中介方法、支持中介的代数、查询重写算法和促进查询优化的转换规则。

Accessing heterogeneous data through homogenization and integration mediators

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.
