Hi, I should give the master an ER diagram for a online shop. the thing is she didn't teach well and I didn't study well too. so now I'm on trouble designing my ER diagram. I searched on web and best thing I found is this: http://s7.picofile.com/file/8248452418/photo_2016_04_23_23_02_02.jpg
but it's not good enough. also there should be a "product category" or "product group" in the ER diagram. I wonder if anyone have done such a thing for University lessons. any kind of help will be appreciated!

EDIT: Also, I presume this is relational databases? Or conceptial?

just do a shop that only sells early access games, that way you don't have to deal with things like having developers or a product.
or a store that only sells non-refundable virtual gift cards for said store.

If you want to make a diagram for an online shop, you need to determine the shop'si policies. Such as how many products can a client purchase at a single time.

Its complicated to do a er without to know the conditions for the relations. example the cars part..
When i had to do er i tried locate id_unique and separate the entities and use a sense common with relations 1:1 and 1:n, etc
