Why not just create something using excel files. Each file can be a table on its own. Make sure one column is a ID column and to link them to each other you have to have one tables ID column placed in the other. I had 5 excel files for my own class project. Just be creative you don't really need a database.
Why don't you use a binaryload from an existing .qvw file (plenty on the demo site or in the default examples folder c:\program files\examples\documents)?
If you're not sure how to do this then go to edit script in your document and click on the QlikView file button, browse for a .qvw file and then simply reload. This will load the complete data model but no layout from that .qvw file.
Did you know we have a program called "Qlik Academic Program" in which we will provide you with a free license and resources to use to add QlikView to your curriculum?
