According to the Oracle FAQ page4, "ORDS is a Java application that enables developers with SQL and database skills to develop REST APIs for the Oracle Database, the Oracle Database 12c JSON Document store, and the Oracle NoSQL Database." ORDS is not a low code development platform, nor does it store, manage or index JSON documents. ORDS also does not create servlets for the Data Dictionary.

ORDS stands for Oracle REST Data Services, which is a Java application that enables developers to access and manipulate data in Oracle Database using RESTful web services. According to the Oracle documentation2, "Oracle REST Data Services (ORDS) bridges HTTPS and your Oracle Database. A mid-tier Java application, ORDS provides a Database Management REST API, SQL Developer Web, a PL/SQL Gateway, SODA for REST, and the ability to publish RESTful Web Services for interacting with the data and stored procedures in your Oracle Database."
