In this short video we'll examine table relationships in a number of different Access applications including the classic Northwind database.  Proper table relationships are foundational to data accuracy and peak database performance.  We'll define how one-to-many relationships work with the primary key field and foreign key field, discuss one-to-one relationships, and also show how to create many-to-many relationships using junction tables.  We'll also examine Lookup tables, and how they help define and constrain values for a field.
