TL Omnis. And another RAD old-timer - Omnis was one of the first RAD environments I played with and it was quite unusual for its time. No "real" programming back then, just GUI tools for wiring and connecting in combination with calculated fields, but these were very powerful. Very strong focus on graphical tools for various purposes (DB design, relationship management, reports, forms, etc.). It's quite amazing what you can find when you dig a bit. By the way, there is a free standard version of the environment, so you can just take a look at what it can do today.
