Aggregation Transformation of XML Schemas to Object-Relational Databases

As XML has become an emerging standard for information exchange on the World Wide Web, it has gained attention in database communities to extract information from XML sees as a database model. Recently, many researchers have addressed mappings from XML structures onto database structures. In this paper, we present the way to transform the XML encoded format, which can be treated as a logical model, to the ORDB format. Firstly, the paper discusses the modelling of XML and why we need the transformation. Then, a number of transformation steps from the XML schema to the ORDB, with the emphasis on the transformations of aggregation relationships are presented. Two perspectives regarding this conceptual relationship (existence dependent aggregation which consists of homogeneous and ordered composition and independent aggregation) and their transformations are mainly discussed.
