DB schema example

Hello.
I want to apply AB test to a shopping mall, so I chose Growthbook.

However, I have no experience with AB testing, so I don't know how to create a DB Schema.

Sorry, but could you give me an example of the schema?

I want to get data related to events, pages, orders (purchases), and carts.

Additionally, what information does the device ID store?

Thanks.
