calendar, sql database features, attribute calculation (user defined functions) ...

I don't see URp and SQLNotes being in competition but complementary.

If both are based on a database, URp is geared toward single-user information integration (text, web, email, files and folders). SQLNotes is more geared towards organizing (text, numbers, dates, database-like lists, web), analyzing (calculations, summaries), sharing (multi-user) and project management (tasks, due dates, Gantt)
