Introduction

Whether you're an Oracle Data Integrator administrator or developer, there are frequently times when the best solution to a given problem may involve the use of variables. Knowing how to declare, set, refresh, and pass variables between the various ODI components will enable you to work through even the most complex design problems.

To read more about the details of variable usage within ODI, refer to Chapter-12, Section-2 of the book Developer's Guide for Oracle Data Integrator, which at the time of writing could be found on the Oracle web site shown here:
