Open Source Native XML Database Architectures - a comparative study

Text-based and model-based architectures are two models used by Open Source Native XML databases (NXDs) to physically store collections of XML documents. The question is: which one of these two models is better in terms of performance. This paper provides some insights into these two NXD architectures. Additionally, the metric performance comparison of text-based and model-based architectures it observed on three Open Source NXD products specifically dbXML, eXist, and Bekerley DBXML that implement either of these two NXDs architectures. The different methods used by each of these Open Source NXD products to manage collections of XML documents are discussed and time taken to store different number of XML documents is analyzed and compared.
