Smartclient LGPL Restdatasource - Map data from an SQL query

Hi,

We are planning to use Smartclient LGPL in our project ie. the client-side data integration approach and Model and Controller layer is already handled with in our project. Understanding is to use Restdatasource in this case to display the data in UI. Can you please help to identify how to map the data retrieved from an SQL query to the Rest Data source?

Regards,
Priya
