Question : Data Modelling

Hi all,

I am trying to identify the attributes of data store of DVD shop. However,  the following text makes me confused. I have five entities such as member, loan, DVD, copies and reservation. Member stores member details and so on. Text mentions about rates. each DVD prices are determined according to rates. For example, new DVDs has the highest rates. But I don't know how to show the rate attributes under which entities?

Thanks,

Loan is the right place, yep. The calculated fields will be created in a query later on. The query will then be based on whatever tables you like, so you can link the DVD to its appropriate dates using this query.
