N,
Domain aggregate functions like DMax, DMin, Dcount take as arguments
a field, a table, and some criteria. They traverse the entire table, select
the records that fit the criteria, and then do the sum or count. They
have a reputation of being slow, but unless you have very large tables
they work just fine.
Normal functions? What's that? If you mean InStr, Length, etc. They
are just functions that are applied to a single data element (as opposed
to an entire table).
