Great vid. thanks. In the STAR design, would the vendor table be linked directly to the fact table with the ProducId separately from the products.? That would not be normalised. As you have it, the STAR design looks perfectly normalised.

Can you explain what you mean by “normalized” vs “denormalized?”
Patrick B. (2 months ago)
I know this may be late and you perhaps don't need it anymore but when he says denormalized, he means that the dimension tables are more grouped together. For example, you can group 3 tables like Client, city, and province into 1 client dimension table for simplicity when using OLAP but, you can also normalize tables which is the opposite and u split tables into several, this reduces redundancy sometimes. Hope this helps

Didnt understand anything because I don't know what "Normalized Dimension" means it was repeated a million times in this video.

A table Normalized means donot repeat dependent data - so create a foreign key table; Normalized dimension - a dimension table which has some child tables (to be normalized== to avoid repetition of data)

The difference table is good but maybe you shouldn't say exactly what is written, I can read it. Some facts or information related to it would be more helpful. Keep up the good work
