   First off, even today, no application would edit a 16GB file in memory. That   
   would be asinine.   
      
   Nothing says the *entire* file has to be in memory at the same time. It is   
   called windowing ... a technique very commonly used.   
      
   Same thing with DB2. If I run a SQL query, and open a cursor on that query,   
   nothing says the result set has to all be in memory at the same time.   
      
   Think outside of the small box you seem to be stuck in.
