Hi Brain,
- Constraints require Normalization and there are deviations in design

projects prefer not to normalize above 2F, some go till 3F.
Non 3nf will lead to data errors.
For that matter, not going to 4nf will lead to data errors.
There are alternatives for reporting.
Materialized views for instance.
