PostgREST: Automatic REST API for Any Postgres Database. PostgREST serves a fully RESTful API from any existing PostgreSQL database. It provides a cleaner, more standards-compliant, faster API than you are likely to write from scratch; Pg_timetable: PostgreSQL Job Scheduling.

It is completely database driven and provides a couple of advanced concepts.
PostgREST and Pg_timetable can be primarily classified as "Database" tools.
