Is this part of product dimension

Question

Im building a product dimension of all the dresses designers can sell. each dress can have multiple sizes and
colors a cost price and rrp price and also a size surcharge, so size 14+ could be an extra £30. these are cost designers pass on to the retailer as they dont sell direct to the public, in effect they sell to the retailer
retailers also then have the ability to apply a sale price (their mark up) to the dress and then also a size surcharge.
my question is, should these sale price and retailer set surcharges be in included in the product dimention.
if not how would i calculate the actual sale price to compare it the cost price etc.

Answer 1

I have a question. I am just studying this DW/BI theory based on your comment to a post I made under the T-SQL forum. I get the impression that data warehousing, from the database standpoint, is generally considered a separate database from that of the database
that daily operations are ran from (or at least separate tables?), and that ETL processes are used to pull the data from the daily operations database/tables into the data warehouse database/tables. Is this why, you would suggest that the particular data that
the OP is asking about would be in a sales fact table verses in the product dimension table or maybe even split out into their own 'dimension' tables (colors, sizes, surcharges) related to the products dimension (snowflake?)?
If I'm understanding this correctly - for small operations (which I am) it seems more realistic to have these historical, slowly changing dimension (if that's what this example would be), tables be in the same database with the dimension tables also being
the tables frequented by the daily use front end users. If this is the case, then would it make more sense to keep the data the OP brought up in the products table or in related dimension tables in a snowflake design? Then maybe also include those details
in the fact table for historical analysis of time as well? Like maybe the dimension tables being used for type 1 changes and the fact table being used for type 2 changes?
I am proposing, and asking. I'm trying to take this all in and this question brought up by the OP is an issue I have been trying to think through as well.
