RE: Separation of Presentation, BL, and I/O Tiers

I am going to ask the dumb question.

What is a MODS?  It sounds like it is a Multiple Occurrence Data Structure?
But since I have used one only once I am not sure if that is the correct
acronym.

Sorry if this question was answered earlier in the thread.

MODS can be based (and therefore dynamically sized) just as arrays can.  The
limitation (as for an array) is that you must define the number of
occurrences as the largest number you will ever need.  I like the technique
because it has the added advantage that you can have multiple definitions of
the DS and map them to individual occurrences of the MODS so you simply
directly compare multiple occurrences.

You can also use things like the C qsort and bsearch routines to sort and
search the MODS.
