I’m confused about the terminology.
If metadata is about data about data while column already defines what information it’ll display for each row, why do you need metadata?
For example, there are columns named Airline Name, Model, Number of passengers, this already defines data about data, correct?
In: Technology
In your example, metadata would be who entered the information, where was it collected, how, when, what other tables it links to, what transformations were used etc.
