One-to-many classification

Understanding the difference between a one-to-one and one-to-many relationship is a useful skill. In this exercise, consider a set of tables from an e-commerce website. The hypothetical tables are the following:

• A customer table with information about each customer
• A cust_tax_info table with customers unique tax IDs
• An orders table with information about each order
• A products table with details about each unique product sold
• An inventory table with information on how much total inventory is available to sell for each product
