In this video we'll update our treeview to use the SQLite3 Primary Key ID number for each record instead of the dummy ID number we created earlier.

Primary keys are unique ID numbers that SQLite3 creates for each record in the database. It's important to use those ID's when referencing a record because they are unique. There may be 10 John Elder's in the database, but there is only one John Elder with Primary Key 12 (or whatever).

In this video we'll update our treeview to use those Primary Key ID Numbers.
