Data types are like guidelines that we give the columns, or fields, to follow so that they store the right kind of values.

Can you select a data type that we can use for so-called strings?

Ah, yes! name is a TEXT-type field for strings, while age is an INT-type field for whole numbers and height can take decimal numbers of type FLOAT.

Psst: we'll go further into these data types a little later.

Yikes! Strings are just another way of describing letters or words. 'age' and 'height' are actually numbers, aren't they?
