When did Magento decide that supporting multiple RDBMS was necessary?
From the first release of Magento, we intended to make the platform cross-DB compatible. We want developers to be able to run Magento on a variety of different database vendors. The initial architecture was designed with this feature in mind and, for several good reasons, MySQL was chosen as the base RDBMS to be supported.
So why is now the right time to begin supporting multiple RDBMS?
A lot has changed. Magento has experienced tremendous growth since those early days. Magento always focuses on providing a lot of features out-of-the-box with the ability to

Why is supporting multiple RDBMS so important to Magento’s recent version release?
The Magento Community 1.6 / Enterprise 1.11 release fulfills the dreams that our system architects had four years ago -- giving our users a platform that is capable of communicating with the database of their choice. With the simplified and refactored DB-abstraction layer, the implementations of Oracle and Microsoft SQL Server support, and the capacity to allow developers to automatically make their customization and extensions cross-DB compatible, we accomplished our goal of providing a cross-database compatible eCommerce platform.
By releasing this guide, we welcome everyone to obtain viable, technical information on the RDBMS changes we have made, so that developers can learn how to get the most from working with Magento in their system.
