You create a relational database by first defining a relationship in the
master file. Then you add the fields to display the data from the related
file in a layout of the master file. You can then work with the data in the
related fields in all modes when you work with records in the master file.
When you type a value in the match field of a record in the master file,
FileMaker Pro uses the relationship to find all the records in the related file
whose match field contains the same value. Then it accesses data from the
fields of the related file in the current record of the master file. When the
related field is in a portal, values from all related records are accessed.
Note You do not need to place related fields in a portal unless you want
to work with data from more than one related record.
