Setting up a relational database with existing tables (databases)
I am using FileMaker Pro 10. I have already established 3 databases, each of them consisting of 1 table with hundreds of entries in each table. Each of the 3 tables have one unique field that can serve as a primary key although it is not designated as such, at least that I know of. Two of the tables have two fields in common. Two of the tables have 1 field in common. What are the initial steps I take to set up a single relational database joining these three databases (tables)??
