What are tables, rows and columns in a database?

A table holds one kind of thing, like customers. Each row is one item (one customer) and each column is one detail about it (like their city).

In real life

Think of a class register: the whole sheet is the table, each line is one pupil (a row) and each heading, like "Name" or "Age", is a column.
