# Overview

Feathers database adapters are modules that provide services that implement standard CRUD functionality for a specific database using a common API for initialization and settings and providing a common query syntax.

Important: Services allow to implement access to any database, the database adapters listed here are just convenience wrappers with a common API. You can still get Feathers functionality for databases that are not listed here. Also have a look at the list of community database adapters
