[ofelyahakobyan]

The primary key in the relational model can be of any valid data type, numeric, string etc. MySQL server also supports that. So you can define a primary key as a string. Also it is possible to have composite primary key. For example in the students table, student roll number and student group number together can uniquely define each student row. So that 2 fields may compose a primary key.

This video couldn't even solve the 1NF and the guy moved over to a different example. This makes no sense
