I think he is telling that I should avoid entities of multiple entities because he mentioned another example after "Inventory" example and said you can not represent a medical history of a patient with one entity because it consists of "appointments" as an entity and "treatments" which is another entity.

- he is talking about designing a relational database for OLTP not OLAP as I remember.

thanks for subscribing.
