Products in Zoho CRM

Products in Zoho CRM

I have center that teaches children.  I would like to be able to track and report on which courses they are purchasing.  I want to be able to answer these questions:

  1. Show show me all parents who purchased product "X". 
  2. How much revenue did "product x" bring in. 
What is the best way to do it.  I am thinking the products module isn't really for doinkg this.
