Abstract: This paper presents a performance analysis of strategies for storing XML data sets in relational databases, focusing on XML datasets that are a combination of structured and semi-structured data. The analysis demonstrates advantages of a hybrid approach combining structure mapping and XML data type instances. However problems remain with current technology with regards to scaling of the approach for large data sets. Also, anomalous results are identified and a threshold at which the cost of data shredding out weighs the advantages of structure mapping. 1
