Fiori - Create oData Model and Creating Customized App

Dear All Gurus,

This may be too easy question for you all but as a layman need your expert advise on this.

Requirment

Create a customized app/oData Model for  'Z' table in ERP server (CRUD operation)

I was able te to  get an Understanding about oData Model - CRUD operation for ZTables referring below Link. (Thanks for Chandrasekar Mahajan for the Blog)

Let’s code CRUDQ and Function Import operations in OData service!

But howabout Ztable in ERP ? Can we use RFC for this and how to integrate this for Ztable?

Thank you...
