XML Performance question
Following the XML for the last couple month, I am surprised how little attention is paid to performance. My optimistic personality leads me to the conclusion that performance is not an issue. :) However, I would be very interested on an expert's guess on the following problem: Assume the following XML document: <PORTFOLIO> <ACCOUNT MANAGER="Joe Smith" ID="000001"> <AUDIT DATE="03/31/1999"> <SECURITYDESC> <SECURITY> <CUSIP>0815</CUSIP> <PRICE CURRENCY="US">4289.23</PRICE> <TRADEDSHARES>4289.23</TRADEDSHARES> </SECURITY> </SECURITYDESC> </AUDIT> </ACCOUNT> </PORTFOLIO> Each document will contain about 10^4 <SECURITY> elements each will contain between 10 - 10^2 child tags, and I have to handle about 10^2 documents a day, i.e. we're dealing with 10^7 to 10^8 tags. So far, the benchmarks I've got are pretty devastating. I have to visit every sub-element of <SECURITY> at least once during the number crunching and I cannot keep everything in memory. I am considering one of the XML repositories to help me with the job. Any comment would be much appreciated. Jens xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
