For Developers and Software Engineers:
Joomla is Object-Oriented Designed - Unlike Joomla's main competitors: Drupal and WordPress, Joomla, is an Object Oriented Designed (OOD) CMS. Object-Oriented Programming (OOP) takes the view that what we really care about are the "objects" we want to manipulate rather than the logic required to manipulate them. One of the principal advantages of object-oriented programming techniques over procedural programming techniques is that they enable programmers to create modules that do not need to be changed when a new type of object is added. A programmer can simply create a new object that inherits many of its features from existing objects. This makes object-oriented programs easier to modify.
For Developers and Software Engineers:
Joomla is MVC - Also unlike Joomla's competitors, Joomla's architecture is MVC. Model–View–Controller (MVC) is a software architectural pattern for implementing user interfaces. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways that information is presented to or accepted from the user.
