Abstract :
In this paper, we present the nested relational sequence model (NRSM), which is an extension of the nested relational data model in order to handle XML data. We also introduce a set of algebraic operations pertaining to the nested relational sequence model in order to handle XML data, to manipulate XML documents via NRS relations. We demonstrate NRS operations by examples and illustrate how XML queries can be formulated within the NRSM. We also introduce the ongoing work of translating XQuery into NRS operations.
