Summary
You should now be comfortable with the notions of variables in ODI and how to leverage them to operate in an environment that can be extremely dynamic.
We have seen in detail the following elements:
How to create variables, and how the different definitions impact the usability of variables
How to use variables in models and interfaces so that the same code can be used even in a dynamic environment
How to use variables in Packages and Load Plans as decision points or branching points
We can now look into the different steps required to build your processes, from connectivity to the source and target systems, to the required transformations and loading techniques. As we cover these elements in the following chapters, keep in mind that you can use variables in most places.
