Abstract

This paper proposes a new query pattern-based relational schema-to-XML schema translation (QP-T) algorithm to resolve implicit referential integrity issue Various translation methods have been introduced on structural aspects and/or semantic aspects However, most of conventional methods consider only explicit referential integrities specified in relational schema It causes several problems such as incorrect transformation, abnormal relational model transition, and so on The QP-T algorithm analyzes query pattern and extract implicit referential integrities through equi-join between columns The QP-T algorithm is based on a concept that columns related to equi-join in relational schema can have referential integrity The most distinct contribution of QP-T algorithm is to enhance extraction of referential integrity relation information for translation Therefore, the QP-T algorithm reflects not only explicit referential integrities but also implicit referential integrities during RDB-to-XML translation The QP-T algorithm also prevents XML documents from incorrect conversion and increase translation accuracy.
