Answer / muttaiah
Hi,
One difference is how we process the records.
In flat file we can process records only sequentially where
as in Vsam we can process sequentially(ESDS), random(KSDS)
or dynamic(RRDS).
That's why most of them prefer vsam. since we can access in
all modes.

As the name suggest - VSAM - Virtual Storage Access Method - it is the Access Method that is major difference between VSAM and FLAT file.
