" That's 13Gb of data, right?"
Depends very much on the " Average width per variable", as seen in
http://www.stata.com/support/faqs/data/datacalc.cgi
If they were all just binary vars, the dataset described by Jibonayan could
be below 2G.

That's 13Gb of data, right? If you really want to put everything into
memory, then you would probably need a computer with 24Gb of RAM. I don't
really know if you can buy anything like that in the desktop format, and
what kind of OS you would need to look at, although I am sure there are
clusters with much larger memory capacities. If you only need subsets of
that data set, then you could
use <list of the variables that you REALLY need> if <subsetting to the
conditions you REALLY want to analyze> using <this huge data set name>
That way, you may have a data set of a more realistic 2Gb size that you can
work with on a 4Gb RAM machine.
