Doesn't anyone else see something wrong with THREE different languages with
significantly differing syntax that have roughly the same functionality
(querying) with yet NONE have update or delete semantic? However some people
think that the time has come for XML databases? Interesting..
PS: IMHO, until someone comes up with a language with simple
SELECT-DELETE-UPDATE semantics, XML databases will be the OODBMSs of the new
millenium. I remember being introduced to XML and thinking that the concepts
behind relational databases were more complex than those behind the
hierarchical structures that encompass XML, amazingly enough the W3C has
proved me wrong by producing increasingly complex languages that supposedly
deal with handling XML in databases yet have much less functionality than a
simple language like SQL. *sigh*
