- Once you've completed your data modeling exercise,…you will have determined what tables…you're going to need in your FileMaker database,…as well as what relationships…are going to be needed between those tables.…What you'll need in order to create relationships…is something that could link each related table together…so that each table has to have a little hook in there…that allows that connection.…In relational databases,…you're gonna connect two related tables together…using special fields defined in each table…and these fields are called keys.…A key field is just like any other field…that you're defining in your database,…but unlike these other fields,…they perform special functions.…
Key fields come in two different types…and each type has its own function.…There's the primary key and the foreign key.…These are two more pieces of vocabulary…that you're gonna hear a lot in this title,…so it's a good thing to understand what they are now.…Let's look first at primary keys.…A primary key is a field that gets defined in a table…
