Batavi is an open source webshop under the GNU General Public License. The development of Batavi started in 2007 inspired by a preliminary osCommerce 3.0 version, a version that seemed to be never finished by the osCommerce team. In Batavi, an Object oriented design model is adopted, and on a functional level XML-EDI integration with the systems of suppliers is a lead theme, as most merchants don’t run ‘standalone’ webshops. This distinguishes Batavi also from other webshops likePrestaShop, Zen Cart and Magento. Batavi is developed on LAMP (software bundle), especially PHP and MySQL, and adopts a three layer model in which design objects, code and the database are strictly separated. From a designer perspective, this creates the advantage of easy manipulation of template objects, without the need of adapting code.
