Hi,
I presume you are talking about the recorded demonstration in Unit Structured Data Objects.
This demo - like many others in this course - uses prepared development objects that you cannot expect to exist in your system.
I know this is different in some other courses, but in this course the demos are meant for watching. they are not recorded exercises.
If you are looking for hands-on experience, please wait for the end of the unit and you will find a step-by-step exercise on the topic.
Hope that clarifies the issue.
Happy learning!
