Database vs Cards

Geoff:

This sounds like what I'm looking for.  However, I have NO experience 
with storing data in arrays - other than the very simple "lines & items" 
approach frequently utilized in Hypercard - and this mostly for short 
term storage in local variables.

I would certainly appreciate if you could possibly give a small example 
of how data might be saved to such an array and then how a particular 
record might then be displayed.  Also, how would searching and sorting 
be handled in such an arrangement?

Like I said, I would really appreciate help on this topic as I'm really 
trying to break free of my old Hypercard way of doing things.

Thanks in advance,

Alan
