Database Drivers

This module is a set of base component and connectors to integrate Doctrine ORM with Drupal Core. The Doctrine Object Relational Mapper sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL.

This is a driver that allows Drupal to use an Oracle Database as the primary backend.

To create drupal nodes in a MySQL backend from Oracle tables you should use something like migrate project, which is a robust data migration solution.

The CouchDB module provides API access to any Couch Database. The API exposes a majority of the Database, Document, Design and Views API. The CouchDB module when enabled does not do anything. It provides a library to build additional functionality or applications.

The couchdb_watchdog module is a sample implementation of using Drupal with CouchDB.

Please help solidify the development release into a full 7.x release by logging issues and testing the module out.

MongoDB integration for Drupal. This is a collection of several modules which allow sites to store different types of Drupal data in MongoDB.

Forena is database report writing software built on the Drupal platform. Forena is built of the idea that if you can write the SQL necessary to get the data out of a database, it should take very little work to get that data out on the web. It is designed to leverage knowledge of HTML, CSS, SQL and Java Script to help you create rich interactive web reports.

Note: Before trying out forena make sure you have private file systems properly configured. It doesn't need to be set as the default delivery method, but it does need to be configured.

One of the most exciting new features about Drupal 7 is the object orientated database layer, or Database: The Next Generation (DBTNG) as it was code named. For the first time in Drupal's history, you can now connect to several different databases of different server types at the same time. All using Drupal's database framework.

This special database engine implementation handles failover between a set
of database connections. The current master is centrally stored in a
pluggeable failover agent.
