Just add two data columns, previous and next to your products database.  

Otherwise you could write some tag that would apply whatever sort of
logic your catalog requires, eg alphabetic, size, by code.  You'd probably
want to cache the result set for that, because you will have to select
all products each time for anything complex.  Build a file in the background
like
code    previous    next
and just pull the line for the code in question.
