Since Darren Terry published his infamous article on saving found sets for future retrieval in 1996, a lot has changed in FileMaker. The additions from the last thirteen versions of FileMaker offer many alternatives for amassing unique identifiers. The differences in collection methods mostly come down to speed but there are a few other considerations that shouldn't be overlooked. However, restoring records remains the same, relying on the humble Go to Related Record (GTRR), and will not be discussed in this article. I also won't be able to point specifically to the originators of the additional methods for collecting unique values as they have been lost in the vastness of time. For all I know, I was the first to come up with some of these techniques.
