    Taking 3NF into BCNF?

    I've been trying to decompose this table that is already in 3NF into BCNF, no luck yet though, any ideas?

    Hmmm.... that's a tricky one. What is your business requirement that is driving this? What do you expect to gain from BCNF?

    you could start by explaining what is the dependency of employee number on warehouse and/or vice versa

    The employee_number refers to the employee that works at a specific warehouse handling the inventory of parts. So given the employee_number you can tell the warehouse.

    in that case, i don't think your table is actually in 3NF
