I am creating an employee database. Currently I have a main employee table, and as I have viewed the last few lessons I realized that I need to take some things out and create separate tables. I am struggling with how to deal with the list of 12 certifications and their expiration dates that each employee may have. Currently I have fields for each cert and its expiration date, but it seems like that does not follow the rules of normalization. Should I create a many to many relationship? How would I use that to still keep track of expiration date? I would appreciate any feedback before I go farther in development. Thank you
