Magento is an open source e-commerce web application that was launched on March 31, 2008 under the name Bento. It was developed by Varien (now Magento a division of eBay) with help from the programmers within the open source community but is now owned solely by eBay Inc.
Magento was built using parts of the Zend Framework.It uses the entity-attribute-value (EAV) database model to store data.
In November 2013, W3Techs estimated that Magento was used by 0.9% of all websites.
Magento Community Edition is open source software and can be downloaded for free. Developers can modify the core code and add features and functionality by installing extensions from the Magento Connect marketplace.
Businesses using Community Edition to run their stores will want to have access to their own Magento experts, since Magento does not provide technical support for this software. Answers to many technical questions are available on our user forum.
Small businesses that prefer to have access to technical support and a more comprehensive feature set should consider Magento Go, our “commerce in the cloud” solution. Mid-large size businesses that need support, additional features and our best performance should consider Magento Enterprise Edition.
