Radicore does not use any naming convention, such as an 'fk' prefix, to identify foreign keys. A field becomes a foreign key whenever it is used in a relationship regardless of its name, and it can be used in more than one relationship.

The Radicore framework "knows" that a field is a foreign field when the relationship details are entered into the Data Dictionary and exported to the application. This information is then made available in the $child_relations and $parent_relations arrays within the '<table>.dict.inc' file

When you are associating a lookup array with a field it is a good idea to have the lookup name the same as the field name as the code has to determine the field type before being able to add a blank entry to the array.
