Oracle REST Data Services (ORDS) makes it easy to develop modern REST interfaces for relational data in the Oracle Database, Oracle Database 12c JSON Document Store, and Oracle NoSQL 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.
ORDS is included with both Oracle Database and Oracle SQL Developer installs. It is supported in Weblogic, Tomcat, Glassfish, and also as a standalone application running Jetty in embedded mode.
