XQuery Processing in Natix with an Emphasis on Join Ordering

We give an overview on how XQuery processing works in our native XML database system Natix. After a brief description of the query compiler we focus on the aspect of join ordering when generating query execution plans. Here we show that better plans can be found when extending the search space of the plan generator.
