The order in which we create our tables is significant. Any table referred to in a foreign key relationship will need to exist before the relationship is defined. Because of this, it's best to start with your lookup tables and follow the chain of one-to-many relationships until all the tables are created. In our ERD, that takes us from roughly the upper-left to the lower-right.
