    Duplicate records are the scourge of any database. As developers we are constantly reminded about the need to create security controls and user interfaces that eliminate duplicate records. Since there is really no way to prevent users from creating duplicate records without extreme controls, which creates a whole different set of data entry hostility issues, you need to create a method to find duplicate records. With FileMaker Pro 7 you no longer need any extra fields to mark records or calculations that concatenate fields together to create duplicate record criteria. The entire process can now be self-contained within two basic scripts. For more advanced developers you can also allow the users to dynamically define the duplicate record criteria.
