XML Uses
-
Hi there, I am very new to the new technologies (.NET and XML etc) because my work as a developer at this company does not allow for further training..... My question, I work alot with databases (access mostly).... how will XML make my life better? I have read in MSDN about it a bit, but would like to know the exact uses etc, because I am getting confused by what other people tell me. Thanks

There was a discussion about this in this earlier thread. Basically what's nifty about XML is the fact that it is plain text, making it very generic. The basic XML concept is very simple, and it has a great many uses.

As far as uses go you have to open your mind a little. One that is very attractive to me is being able to integrate data in a more data driven nature. Take a look at the Apache Cocoon framework for a sample of what I mean by this. To be conscious that you are ignorant of the facts is a great step towards Knowledge. Benjamin Disraeli

XML is awesome for several reasons. Number one is that it is standard. This is the prime reason XML should be considered for anything at all. Next, it is rigid, and fails with a parse error if it is not. This strongly encourages clean files, and helps with performance, among other things. Another thing is XSL. Any standard XML document could be transformed into any sort of file with this powerful technology. Raw ASCII, HTML, DHTML, perhaps even things like postscript and CSS. The XmlDOM and XPath. This lets any program work with XML in a standardized way. Most programs I make with Xml support use the Dom extensivly.

XML, the downside: -XML is a lot slower when searched, compared with normal database queries. -XML adds a lot of overhead, means bigger DB -XML parsers are usually slow -.NET implementation of XML is REALLY SLOW and requires managed code, which sucks hard XML, the upside: -universal -simple tree structure: even a child can read it -can be created/edited with NOTEPAD, the best application ever written //////////////////////////////////////////////////////////////////// // NOW THE UPSIDE THAT YOU WERE ASKING ABOUT // // you can put in a single DB cell a complex and dinamic structure! // That means that the information saved in the DB can have a dinamic structure WITHOUT changing the DB!! ////////////////////////////////////////////////////////////////////

Zip loves all those repetitive tags. So for transfer it is not as big a problem as some people make out. Of course when you are working with the XML it has to be unzipped and then the size can be a pain. regards, Paul Watson Bluegrass Cape Town, South Africa The greatest thing you'll ever learn is just to love, and to be loved in return - Moulin Rouge Alison Pentland wrote: I now have an image of you in front of the mirror in the morning, wearing your knickers, socks and shoes trying to decided if they match!

The problem is when you are working with a speed-demanding DB system, when the client workstations need almost real time feedback from the DB. If i want to conduct a search inside each XML string (if you treat it as a stream) for each row in a DB table, and you also have to unzip it first, the overall system performance is heavly reduced. For transfers, no problem. I agree with you. Best Regards
