Storing XML

Tuesday, May 25, 2004, 12:17 — 0 comments Edit

I’m currently doing research on how to store XML with object-oriented means. It’s of course rather trivial to store XML somehow. The interesting question is which system makes most sense if the XML is to be queried using XPath or XQuery expressions. <!–more–> Just to write down some of the ideas:

Also a lazy update of pointer lists might be nice. Every XML node keeps a list of pointers to the nodes on its axis like siblings, predecessors, children, successors etc. which is kind of virtual. It’s only created when needed and updated if certain timestamps (which have to be somehow kept in the data dictionary) are updated.
