You can use this database for various purposes, such as:
learning SQL language on your own
preparing books, manuals, and courses on SQL
showing Postgres Pro features in stories and articles
When developing this demo database, we pursued several goals:
Database schema must be simple enough to be understood without extra explanations.
At the same time, database schema must be complex enough to allow writing meaningful queries.
The database must contain true-to-life data that will be interesting to work with.
This demo database is distributed under the PostgreSQL license.
