in one of my project ,150 to 200 customers r there. .and i have to maintain record of each. There r 3 separate programs on separate machine to update that records.
So options in front of me r:
1 “to maintain 1 file and store all records in the same file” or
2 “maintain separate 150 or 200 files..(each file for each person) “
RequirementSecurity is more imp. Than the accuracy )
so tell me which one is feasible.. and at minimum risk.
My second ques is : Is it possible that 2 programs can simultaneously update records from same file?
Both problems r related to C.
