I am starting a new role, that is (technically) not IT related. I would really like to enhance what's going on with this team by building some dashboards to get around using some of the archaic reporting tools so much. Right now there are at least 6 different reporting tools for similar data that all give you different numbers. I imagine I'll be querying OLAP cubes to do this but my experience in this area is limited. The IT department is a total mess from the outside looking in.
How do I approach my IT department and request access to the data warehouse/SSaS server(s) so that I can set up my own OLAP cube(s) or gain access to ones already made. No one at the company has even been able to explain the infrastructure of the data to me.
My big data experience is beginner level like I said but I imagine it is something like Oracle cloud data and hadoop. Do I just ask about to infrastructure to a VP and go from there? How do I word this so that I don't sound like an idiot, I will definitely be learning as I go but am confident in my ability there. I can justify the business need, the data will be safe.
Any advice would be greatly appreciated on how to word things and make the approach, etc. Thank you.
