Hi all,

I'm designing an application in which i download stock data as a *.csv file, one file for each stock, which contains 10 columns with floats.

I'm wondering what way is the best way to store these data.

Obviously I do not want to keep x files for x stocks since x might become quite large over time.

I have been reading about xml but that seems like an awefull lot of overhead compared to csv.

Since, in a later stadium, I would like to make it open source I would also like to do this in a correct way.

How would you guys solve this? Please give a little motivation so everybody can learn out of the answers.

Thanks a lot guru's

kind regards
