SQL and Data Visualization Insights

MediumSQL · PostgreSQL

Problem

Walk me through the SQL you would write and the insights you would derive from the results, including how you would visualize them.

Use the tables in the schema to produce a concise performance view by listing and month. Keep the answer focused on the result set and the analysis you would present.

Output

  1. One row per listing and month with activity in that month.
  2. Columns: listing_id, month, views, bookings, booking_rate.
  3. Include only months where the listing had at least one view.
  4. Sort by listing_id, then month ascending.
