- An example database schema can be found <aclass="grey--text"href="https://github.com/lerocha/chinook-database/tree/master/ChinookDatabase/DataSources"><u>here</u></a>.
Before doing so, make sure you have a Heroku account. By default, an add-on Heroku Postgres will be used as meta database. You can see the connection string defined in `DATABASE_URL` by navigating to Heroku App Settings and selecting Config Vars.
Tip 1: To persist data in docker you can mount volume at `/usr/app/data/` since 0.10.6. In older version mount at `/usr/src/app`. Otherwise your data will be lost after recreating the container.
Tip 2: If you plan to input some special characters, you may need to change the character set and collation yourself when creating the database. Please check out the examples for <ahref="https://github.com/nocodb/nocodb/issues/1340#issuecomment-1049481043"target="_blank">MySQL Docker</a>.
