Chinook Sample Database
In this post we are going to walk you through how to download and install the PostgreSQL compatible version of the Chinook sample db onto the YugaByte DB distributed SQL database with a replication factor of 3.
The Chinook data model represents a digital media store, including tables for artists, albums, media tracks, invoices and customers. Media related data was created using real data from an iTunes Library. Customer and employee information was created using fictitious names and addresses that can be located on Google maps, and other well formatted data (phone, fax, email, etc.). Sales information was auto generated using random data for a four year period. The basic characteristics of Chinook include:
- 11 tables
- A variety of indexes, primary and foreign key constraints
- Over 15,000 rows of data
Here’s an ER diagram of the Chinook data model:

You can download the Chinook database that is compatible with YugaByte DB from our GitHub repo. The three files are:- chinook_ddl.sql which creates tables and constraints
- chinook_genres_artists_albums.sql which loads artist and album information
- chinook_songs.sql which loads individual song information
We’ve purposely broken up what would otherwise be a very large script. By breaking it up into building blocks, it’ll be easier to see what YugaByteDB is doing and spot any problems (if you encounter them) a lot easier.
``` CREATE DATABASE chinook; ```Let’s confirm we have the exercises database by listing out the databases on our cluster.
postgres=# \l/
Switch to the chinook database.
postgres=# \c chinook
You are now connected to database "chinook" as user "postgres". chinook=#
Build the Chinook Tables and Objects
chinook=# \i /Users/yugabyte/chinook_ddl.sql
We can verify that all 11 of our tables have been created by executing:
chinook=# \d
Next, let’s load our database with sample data.
chinook=# \i /Users/yugabyte/chinook_genres_artists_albums.sql
and
chinook=# \i /Users/yugabyte/chinook_songs.sql
Do a simple SELECT to pull data from the “Track” table to verify we now have some data to play with.
chinook=# SELECT "Name", "Composer" FROM "Track" LIMIT 10;
