Would you design a dashboard for a website

Dear everyone,

I don't know if it is a vague question or not but I have no idea how to do it. I have a small website and some data that I want to track. I want an aggregation for my website where some of the data comes from analytics and others from my Postgresql database. I want to batch job the aggregation in values and be able to view the latest aggregation as an admin dashboard. It is more of a learning exercise than for a commercial purpose.

- How would you store the aggregations for the dashboard? Document database or as files? - What is the optimal standard way to do such a thing? - How to do it as a workflow?

Thanks.
