Magento is a web application framework and CMS (Content Management System) that specializes in building online shopping carts and other e-commerce software. Built using parts of the Zend Framework, Magento employs an MVC (Model-View-Controller) architecture and an EAV (Entity-Attribute-Vale) database model to store information. Magento comes in an open-source Community Edition version that offers developers a basic e-commerce platform. The paid Enterprise Edition has the same code base as the Community Edition; however, it offers better scalability and also comes with enterprise-class extensions and other features, as well as support and training. eBay owns the Enterprise Edition of Magento and sponsors ongoing open-source development of the framework.
