Web Service with Oracle Database

Question

Hi

 

We are developing an android app to display some data from an Oracle database. The data is required to be exposed as a web service .  I have chosen WEB API for the same.

The data from the oracle database is taken as an inner Join from 12 tables.  Each table having approximately 100 to 120 fields

 

In order to get the data to my web service should I create a model for all the fields in the oracle table.

This is my first web service using WEB API.  Can somebody help?

 

regards

Raj
