Dominic Giampaolo worked on Spotlight at Apple, and was the BFS guy at Be... he (along with another engineer) wrote BFS pretty much from scratch for the PR1 release.
Before BFS, was OFS which was an actual database and was horribly buggy, requiring the BTree to be regenerated often enough that it was a "BIOS" level boot menu option on the BeBox running that version's Boot ROM.
A lot of the wonder at BFS stems from the marketing of OFS. BFS only retained the bare minimum features that OFS had, to make the database stuff still exist.
