I think the Zeos component is a great free component for many database
access with single interface (I used it to access database but for small
database, so far it's OK), but lack of developer :(( and I cann't help for
that cause my experience in programming is low

I think the important lack of Zeos component is, it will receive all data if
the resultset is 1000 (for example), it doesn't have a facility to receive N
data first and then if the user scroll down the data it will then receive N
data again (like in Direct Oracle Access component)

Sorry for my bad english.
(Hope Zeos developer is in this mailing list too ^_^)
