RESTful Services in Oracle APEX refer to a feature that allows you to create, publish, and consume RESTful web services directly within your APEX application.
RESTful Services enable communication between different systems or applications over HTTP using standard REpresentational State Transfer (REST) principles.
Oracle Apex integrates REST data sources in classic reports, interactive reports, CSS calendars, and charts.
In this exercise, you will allow an external Apex instance to access your
data through REST.
