PostgreSQL Summary Stats and Window Functions

Here you can access the summer_medals table used in the course. To access the table, you will need to specify the medals schema in your queries (e.g., medals.summer_medals).

Note: When using sample databases such as those that contain course data, you have read-only access. You can run queries, but cannot make any changes such as adding, deleting, or modifying the data (e.g., creating tables, views, etc.).
