Comparing Prestashop , Opencart and Magento depends very much upon the user perspective . e.g
\nPrestashop and Opencart both shopping cart module are fairly lightweight as compared to magento with less table creation in database but from developer point of view Opencart lacks some of the very fundamentals features E.g<\/p>\n
Observer\u00a0 Design Pattern<\/strong>\u00a0 – Opencart Does not Support Observer design pattern as magento does so for creating module in opencart is really a painful task when you need to extend the functionality of the module without affecting the core .<\/p>\n There are third party module and apps like\u00a0VQMOD\u00a0and\u00a0Override engine\u00a0but both of them are not good as magento is . so from developer point of view opencart lacks a lot of key design patterns and structure\u00a0\u00a0.<\/p>\n
