It is the meaning of ORDS.
But what is Representational state transfer ?
Where do we need it?
The Oracle REST Data Services (ORDS) helps to develop/host the RESTful Web Services (develop RESTful interfaces) on the Oracle Database (so that we can represent the relational data in Oracle Database as a RESTful Web Service or can do RESTful Web Service operations like GET, POST, PUT, DELETE which ORDS translates/operates to Oracle Database (tables) as SELECT, INSERT, UPDATE, DELETE).
- You can find much more use cases of RESTful interface provided to Oracle Database by using Oracle REST Data Services.
- Oracle also provides node-oracledb driver as an interface to Oracle Database for web technologies using Node JS. (So, for Oracle JET you can use either ORDS RESTful services or node-oracledb driver).
Hope this helps!
