Feathers database adapters are services that write to a database. Instead of coming up with our own ORM and validation system our official database adapters simply wrap many of the great ORM/ODM solutions that already exist.
Important: We recommend being familiar with the common interface chapter before using a specific database adapter.
Every official database adapter supports common functionality for initialization, pagination and sorting and advanced querying out of the box and can be extended with custom functionality. Errors from the adapters (like ORM validation errors) will be passed seamlessly to clients.
This allows you to swap databases whenever the need arises without having to change any of your querying code or validation hooks and you can even use multiple databases within the same app.
Important: If your database of choice is not officially supported you can still implement it as your own service and get hooks and real-time updates for that database. Also, have a look at the Ecosystem section to see if there isn't a community supported adapter for the database already.
