Of course not, but we hadn't gotten that far. We're talking about (as it turns out) confusion in the use of terms. It appeared to be a discussion about someone thinking that RAID and indexes were a source of redundancy as it applies to 3NF. That is the context in which we were dealing. A discussion of BCNF, 5NF, etc. would not have helped at that point.
