Re[2]: Optimized Search method for DB files. ?

     Security wise, the multiple members concept seems more practical 
     than company key-field. Personally, however, I'd be much more 
     comfortable with separate libraries & files for each company, which 
     could be secured as required. Really, though, I all depends on the 
     situation.

Instead of combining data from multiple companies into the same file, 
have you considered using multiple members? (ie) A member for each 
company. Depending on the company you want to work with, a CL can set up 
appropriate overrides.
