Write a few (rather simple) SQL queries

For an assignment, answer 5 questions which include writing an optimized query.

You should probably set up a small database for testing, with tables generated with dummy data.

I will test your queries' performance.

Window functions will be required, for that reason please use PostgreSql.

If you know your stuff it probably shouldn't take more than an hour.

Notes:

* Experienced bidders only.

* Highly proficient in English.

* PostgreSql.
