A Semi-Structured Data Cartridge for Relational Databases F. Sha, G. Gardarin, and L. Némirovski   View Paper (PDF)   Return to New Applications Abstract In this paper, we present our experiences on managing semi-structured data in relational databases. We use a Java package built on top of relational database for store and query semi-structured data. In this work, we introduced a more complete data model, a flexible storage scheme, and a compact metadata structure for processing regular path expressions. DiSC'01 Copyright ©2002 ACM Inc.
