[Exist-open] Q: NXDBs are mature solution?

[<rc...@wi...>]

Hi!

I'm an interested newbie in NXDB. Weeks ago, looking for information, I
found a list of NXDB, specifically at:

http://www.rpbourret.com/xml/XMLDatabaseProds.htm#native

looking & looking for it seems that all open source solutions want to
implement XQuery in a future ... but not yet! ( between other things )

For the time being they offer Xpath and/or proprietary solutions in
commercial cases and only various commercial solutions like
http://www.mediafusion.co.jp/usa/seihin/sekaiju/index.html   speaks about
transactions, rollbacks ... it seems for the time being NXDB uses are for
limited purposes, true?.

( I hope not to be mistaken but it is what I've deduced from that I've
found )

in your experience, can eXist to exist ( ;-) ) under a B2X architecture? =
or
is it advisable to follow with relational-DB structures?
