Abstract

This paper proposes a new and efficient method to represent, store and retrieve structured documents from object-relational databases. Its main contribution consists of a codification scheme for document structures that assigns codes to documents as an additional attribute. Thus, retrieval conditions on the structure of documents can be evaluated by applying these codes, avoiding traversing object references. The paper also gives some clues to the construction of a repository of structured documents over object-relational tables, so that query conditions regarding the contents, structure and metadata of documents are executed by the underlying database system.
