I want to know your opinion about using data-aware components in projects. Which are the 'strength' and 'weak' points of developing applications(win32 and web), by using Delphi and data-aware components(from Delphi's standard suite or third-party)?
Using FireBird I've worked a lot with IBObjects, which are a mature suite of components and worked very well.
But there are also a lot of other RDBMS (MySQL, MSSQL, DB2, Oracle, SQLite, Nexus, Paradox, Interbase, FireBird etc). If you have developed big projects, on which you've used a lot data-aware components please answer with the database type and data-aware components suite name.
I'm also interested on DB2 (AS400). What components have you used with success, or which components are really a pain to work with?
