# Overview
Feathers database adapters are modules that provide [services](../services.md) that implement standard [CRUD](https://en.wikipedia.org/wiki/Create,_read,_update_and_delete) functionality for a specific database. They use a [common API](./common.md) for initialization and settings, and they provide a [common query syntax](./querying.md).

[Services](../services.md) allow to implement access to _any_ database or API. The database adapters listed here are just convenience wrappers with a common API. See the community adapters section for support for other datastores.
