Enrich our DB model

[goldbergyoni]

The example app DB schema is too simplistic and might not tell the truth when conducting performance benchmarks. It could be great to add a few more fields to the main table and also one more relation.

Before picking this issue, it's recommended to have a short tech planning chat here and only then upon sync to get up to speed.

There are levels of data that we should have:

• Test data - Orders - Rows that are modified by the tests - Created per test - We have this
• Context - StoreInfo - Rows that are related to the test but not modified by the test - Created per suite - We need this
• Metadata - Countries - Rows that just serve as global enums and supporting data - Created once - We need this

@goldbergyoni @DanielGluskin Is this still an issue/was this ever worked on?

I'm interesting in contributing to this repo, since it did so much for me.
