Hello everyone ,
I hope you could help me!
I'm actually in BI project within a company. they have a project management module, each project with a status : in progress or out of time, closing ..
they asked me to create an Olap cube so they could know the number of projects for each status daily.
The question is the following: - Should I necessarily create a data warehouse because I will attack only one module. After I do the modeling it requires 3 dimension table and a fact table that contains only one measure
-if i'm not wrong in this case a Datamart does the same job as a data warehouse
