All my comments are from a newbie user who is learning from scratch, and could provide you insights of how executives need to learn in order to update our knowledge.

Perhaps you could combine VISIO type graphics in order to reinforce your explanations made by hand. As an example, DB, I know there is a special drawing to indicate them.

What is CRUD:

R ead (or select): Get data.
U pdate: Change data.
D elete: Remove data.
