If legacy products took one minute but cost more, my view is they'd keep spending the money and asking for 1 minute. A key scenario here is not so much use of database, but where they are using a database but getting the data out of it as XML (runtime, batch on demand and scheduled batch). This plus where legacy systems took data from database, sent it over a VAN link to another party or over a network to another system and where replacements of that with XML are expected not to include an extra time factor due to a newer technology. Time delay might result in timeouts and lost business (if, say, the document from the database was an order). Pretty standard stuff :-) All the best and many thanks Stephen Green >>> "Michael Kay" <mike@s...> 26/02/07 21:31:14 >>> > > *cough*While I love XML as everybody else on this mail list, HUGE > > perfomances problems that ask for hardware can be a sign on the sky > > some people is using XML where a relational database can be > > better*cough* Well I've had someone recently complaining(!) that Saxon takes 15 minutes to process their 15 Gbyte XML file, and that was my reaction too. But I think they are actually taking a real-time data feed and selecting the data they want to put in the database, which seems a reasonable approach. What I don't know is how much they would be prepared to pay for a solution that processed the same file in 1 minute. That's the test.
