Determining Entities & Data Model

Tea Shop

Mark Tee owns a small shop down a side street in a medium$-$sized town. It only had a few customers $-$ until one day a famous blogger discovered it during his travels and published a post about it$.$ He said that Mark's shop is the best source of tea in the world. Mark now has so many clients that he no longer knows what's in stock. He needs a system that will help him organize his products. This is what he said:

People buy my products all day long and I need to keep track of what I have in stock. I sell various things. Tea is the most important of them, of course. I am very detailed when it comes to tea: I need information about the grade, color, origin... Every single variety has at least some of these properties.

I also sell a lot of coffee, but coffee is different and different things are used to describe it$.$ And then there is the herbal stuff like rooibos or yerba mate. Tea enthusiasts call these tisanes or infusions; they're not really 'tea' and I don't need much additional information about them in my system.
