REALbasic's a RAD tool tool - its compiler produces native executables. And it's a cross-compiler as well, which means you can build from any platform for any platform.
Full database access is only supported in the Professional Edition (at EUR 400). The personal version comes at EUR 75 and can connect to REALSQLDatabase (which also from the RealSoft guys).
Unlike with Hibernate or SQLAlchemy, you must write the DB layer yourself.
