I'm in the early stages of designing a db system which will eventually be 
run on a Prime mini under the PRIMOS operating system.  I've heard that 
the most efficient way to store my data is in one enormous file (about 
3 to 5 Meg). The system I have been asked to study as a possible model 
does it this way.  Using one giant file strikes me as dangerous from a 
data integrity point of view and slow when modifying the data.  Is there
something about the way the OS handles file I/O that makes this more
reasonable?  As I'm just beginning what looks like at least a year of 
work, I'd appreciate any pointers or references.
