Tools like the one you are building often use 3 tiers.. The middle application server is where the code runs that may substitute functionality of procs/ triggers etc..
The down side as paquette said is performance hit.. its either that or hiring extra programmers to make sure your code is compatible with
other databases's procs/ triggers methodology..

good luck :)

On Oracle 7.x there used to be an init.ora parameter "sql_ansi" or something that you could set true/false in order to know if your sql code was ansi compatible or not.

Unfortunately, this parameter doesn't exist on 8i.

For sure, portability is the opposite of performance.

Having your application to work on many rdbms will prevent you to have the Oracle only features. Or you can build a driver per rdbms in order to used each rdbms functionnalities.

Hvae fun !
