ON ANALYZING THE DATABASE PERFORMANCE FOR DIFFERENT CLASSES OF XML DOCUMENTS BASED ON THE USED STORAGE APPROACH

With the increasing popularity of XML data also the need for permanent XML document storage grows. As of today there exist number of different XML storage alternatives ranging from XML enabled relational database systems over a new class of hybrid database systems providing native storage for XML and relational data to pure native XML systems. This paper examines how these different storage approaches perform in respect to the different classes of XML data by devising a new benchmark HYBE with special consideration to certain features of hybrid database systems. First results indicate that hybrid database systems can deliver performance which is (almost) equivalent to native XML database systems making them the optimal choice for small to mid-size companies with the need for both XML and relational data storage.
