Problem

We keep two independent logs for the web product: one row per session in the session log and one row per page view in the page-view log, and a single person piles up many of each. For everyone carrying a real user id in either log, report their total time across all sessions rounded to the nearest minute together with how many different pages they opened.

Summary

Time spent, and everything they touched.
