   Re: [xml-dev] What niche is XQuery targeting?

[ Lists Home | Date Index | Thread Index ]

Treat each (non-xml) data source as one or more virtual XML documents 
and write your query accordingly. This is definitely being done today. 
Remember, performance is relative -- for example, queries in data 
warehouses are usually slower than in transactional databases -- and 
slow performance is better than no application at all, which is often 
the case with these sorts of applications.
