Kexi, created in 2002, in addition to competing with MS Access contains Qt-compatible data-aware widgets: forms, reports, tables, queries. And all designers for them. Also import/export with strong CSV support. C++ developers can employ all this in their apps, this happens from time to time.
Predicate is a database connectivity and creation library, something more than QtSQL and alikes. You can create database without backend-specific SQL. Predicate origins are in Kexi, it competes with Qt SQL and contains many more than it. See https://community.kde.org/Pred.... There's even SQL parser that helps to 100% control of what SQL is passed by your users. It's Qt-only. We're porting Kexi to it these weeks.
So you have visual designers, and data-oriented framework, both interacting with each other.
