SAX is primarily a reading API, not a writing API: reading a document
from a database should be relatively straightforward (assuming someone
has written a SAX driver for the database), and should look exactly
the same to your application as a document read from a file or an HTTP
connection.

You can use SAX as a writer by generating SAX events and sending them
to a client that knows how to create XML markup; in principle, the
same thing should work for adding a complete document to a database
(again, assuming that someone has written a driver), but SAX would not
really be a good fit for doing an incremental update, since it's a
serialized format rather than a random-access one (think of the
difference between updating a file on a harddisk and updating a file
on a magnetic tape; SAX is like the magnetic tape).


All the best,
