Altering an entity
Imagine the business has decided to track more contact details for each fruit product supplier. This information is crucial for businesses like quality control and supply chain management.
Your task is to adapt the suppliers entity to have all the required attributes and a well-identified key so that you can relate later suppliers to the rest of the data model.
The entity suppliers already exist. Below is the code of how it was created:
CREATE OR REPLACE TABLE suppliers (
name VARCHAR(255),
location VARCHAR(255)
);
