    1. COYes, you have unneeded columns (in db nomeclature that's what you call 'fields'). In order_items, total is a calculated value, unless you're not telling us something. Ditto (probably) many of the other columns in orders.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
