Does XML supports huge data?

[varavoorvishnu]

Hi ,
I have an issue wherein 200,00000 datas is retrieved from Flat files.Since the data is read from flat files,the system performance is too low.
1.I would like to know whether the performance can be increased using XML?
2.If so whether XML supports such huge amount of Datas?.

Plz revert me ASAP.
Suggestions appreciated.

I wouldn't use the DOM as that would be very slow for that amount of data. If you want to read the data sequentially for a specific reason then you could use SAX. That is designed for processing large data files.

The switch to XML really depends on what the data is like and what you want to use if for. I wouldn't automatically advise a switch to XML. Could you give an example of the structure of the data and what you are going to do with it?

Thanks,

Hi James,
Thnx for the reply and belated X'mas.
We get huge amount of data which should be shown as a report.Iam not sure abt the format or structure of data.
Since this is our project specification and tht our client faces the problem of fetching flat file datas .They also claim tht takes around 90 hrs to fetch this data.
Hence i posted the request.
Anyway thnx.
