Autonomous Data Warehouse
Autonomous Database includes Oracle's premiere low-code development platform: Application Express (APEX). This provides a low-code development environment that allows you to build stunning, scalable, secure apps with world-class features fully supported by Autonomous Database.
Oracle REST Data Services (ORDS) makes it easy to develop modern REST interfaces for relational data in the Autonomous Data Warehouse database. A mid-tier Java application, ORDS maps HTTP(S) verbs (GET, POST, PUT, DELETE, etc.) to database transactions and returns any results formatted using JSON.
