Magento Interview questions and answers

Magento Interview questions and answers for freshers as well as experienced developers.

1. Explain Magento’s MVC architecture

First of all, what is MVC?

MVC stands for Model-View-Controller. Any application that separates it’s data access, business logic and user interface is called MVC. There can be two types of MVC: convention-based and configuration-based. Example, cakePHP is convention-based, i.e. you just need to follow the instructions of the core system to get your module ready in just few lines. Magento is configuration-based, i.e. you need to specify each and every thing to your module’s config file in order to get it work. Magento has controllers (for request/response routing), Block (for rendering content), Model (for business logic), Resource/Mysql4 (for database operations), etc (for module-specific configuration files), Helper (for common functions), sql (for setup scripts), layout (for connecting block with templates for each controller action) and template/.PHTML file (for Presentation i.e. View).
