Re: [xml-dev] Re: [ubl-dev] Top 10 uses of XML in 2007

Isn't it a matter of high end versus low end?
And therefore applying that to UBL as a form
of XML, isn't it likely that high end commerce
systems will favour a binary translation of the
XML?

It's interesting then to see how Open Office implements
its Base database. Internally it's just an SQL insert statement
with some XML metadata. But of course it's zipped. At runtime
it is made to look and act as a relational database but it is just
text serialised and deserialised, it seems. Not sure what means
in terms of the discussion. If there were nothing to it more than
that it's a wonder all RDBMS databases don't do this. Surely
they use binary for a reason other than to be fashionable.

Do you really believe that databases have anything at all to do with 
compression or saving space? Databases routinely are multiple times 
larger than the actual data they contain. Databases are optimized for 
queries and speed, not for size. Size has nothing to do with why we use 
a database instead of a file system.
