Extracted valuable insights, such as identifying regular customers and calculating business class passenger revenue using SQL queries.
Improved user experience with SQL functions for displaying full customer names and identifying registered customers with bookings.
Utilized GROUP BY and HAVING clauses to pinpoint Economy Plus class passengers.
Employed IF clauses to evaluate whether revenue surpassed a specified threshold.
Created and granted access to a new user for database operations.
Utilized window functions to find maximum ticket prices by class.
