For our in-person sessions, we’re going to discuss the Denmark Statistics project database at Steno Diabetes Center Aarhus, how we’ll use it in our collaborating project DP-Next, and how we can align efforts at converting the registers into Parquet format rather than in SAS format.

This post contains the slides used in the session for talking about Parquet.
