Pukka BDE is unknown to me, but on the case of behaviour and usage within Delphi there's no siginificant difference
betweena Tquery and a Tadoquery. Also linking it to db-aware components, reporting tools etc. is no problem. I believe
thatyou can quite easily replace your Tquery objects with TADOQuery objects, without any major changes. I build almost
everyquery at runtime...
Just my 2 cents (a bit off-topic):
D3? Hmm.. I only started in D4 myself, and got to D7 now :) But I can imagine that the BDE and other data components
area bit outdated in D3. I'm guessing that with the frase "extortionate upgrade prices for dubious enhancements" you
meanupgrading to a more up-to-date delphi version, and not having certainty that your problem would be solved?
Dependingon how the situation for which you are developping is changing (as I believe you are building mostly internal
appsfor NT4 systems), you will be forced to change your toolkit sooner or later. Best is to keep a close eye on that
andbe prepared for this kind of change. Conscider that porting your application(s) could take a lot of time. Looking
fromD3 to the most recent versions, there have been quite some changes. How far Lazarus can take you in this is unknown
tome, since I have never looked into it (sounds interesting though) ;-)
