Chapter 7 – Recipe A Using Oracle as the Database Engine Recipe A: Using Oracle as the Database Engine So far in the book we have taken a database agnostic approach to the tutorials. One of the most powerful features of Hobo and Rails using the ActiveRecord Object Relational Mapping (ORM) capability is that you can usually ignore the back-end issue and focus on solving the business problem.

In this recipe we will provide instructions for these two options: 1.Use and existing Oracle database schema. 2.Download and install a fresh Oracle database and create a schema for use with Hobo.
