In the database schema shown in the images, there are four rows (excluding the header row) representing data entries for four people (John, Jane, Allison, and Anna).

Each row represents a record in the database table, also known as a tuple. The term record refers to a complete set of fields (ID, Name, and Age) for one entry. So, counting the four rows:

Jane

Allison

Anna
