Dimensional models for the datasets:

$1-$ the Star Schema for the CPI dataset

$2-$ The Star Schema for the Wages datasetI got notes from my professor about my star schema diagrams, regarding the first diagram he said the following:

$$It seems like data dataset doesn$$t have the spending per month per location dimension, in this case you might need to add another attribute in the fact table$$

It$$s true that the table originally doesn$$t have the location dimension but I still don$$t understand what the comment means, how would I add another attribute in the fact table? What would the attribute be$?$

And for the second diagram:

$$Fact table: check the data and how numeric measures are reported, you might need multiple attributes.$$

What does that mean $?$ The dataset is very short and only has $3$ dimensions $($ time, salary, gender$)$ how would I add attributes?? Based on what?
