Odysseus:a High-Performance ORDBMS Tightly-Coupled with IR Features

Abstract

We propose the notion of tight-coupling [K. Whang et al., (1999)] to add new data types into the DBMS engine. In this paper, we introduce the Odysseus ORDBMS and present its tightly-coupled IR features (US patented). We demonstrate a Web search engine capable of managing 20 million Web pages in a non-parallel configuration using Odysseus.
