... but DBAs tend to stick to Codd's rules of normalization.
May be this is because Codd put together the basics of the Relational Theory and we are dealing with Relational Databases (RDBMS) 😀
By the way, we DBAs also tend to use normalization only for OLTP systems while rely mostly in Dimensional Modeling for DSS like Data Warehousing.
