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.
