What’s the difference between a table’s schema and its data?
So, imagine this quick scenario. I have a table called Customer, it is a simple table. It contains three people, each having a unique ID (primary key), Name, Gender, and their Age. This is the schema, which defines the data that will be entered into the table.

And, this is the data for the table:
[The image you are requesting does not exist or is no longer available]
Our schema defines the data within a table. Distinguishing between data and schema is Important!
