xml-dev - Re: saving DOM as bytecode in database

[Steve Muench <smuench@us.oracle.com>]

It's certainly possible using a BLOB column,
but I'd recommend you do some benchmarking of 
this approach against other serialization approaches,
like simply storing the "serialized text form" of the XML document
in a CLOB column.

Several of our internal teams found that
the performance of Java Serialization (at least of
a DOM tree!) was appreciably slower than simply
storing the XML as text and reparsing when needed.
(Not to mention that other types of non-Java 
programs can make use of the serialized XML, while
they could not if it were stored as Java-serialized
DOM objects.)

Subject: saving DOM as bytecode in database


| Maybe this is bad idea, but is it possible to
