Demonstration Database

Explore the world of SQL queries

Our team offers a free demo database for PostgreSQL. The subject field of this database is airline flights across various airports.

You can use this database for various purposes, such as:

  • learning SQL language on your own
  • preparing books, manuals, and courses on SQL
  • showing PostgreSQL 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. Current version is 15.08.2017.
