With over 6,000 files Magento can certainly be intimidating at first, but as you get familiar with its architecture you find it less and less intimidating. One main design feature makes it easy to find a class by its class names.

For example, the class Mage_Catalog_Model_Product will be located in the /app/code/core/Mage/Catalog/Model folder and the file name is Product.php. If you ever need to instantiate the class, use Mage::getModel(‘catalog/product’).

Another useful tip about the architecture is that most everything is handled in the various session objects and every operation is basically an event that occurs which then calls a certain method within a particular class. Some of these events are dispatched and can be used by Magento’s event/observer architecture but most are not and therefore one needs to override the class instead.

I know this is very vague but will make sense if you are knee deep inside the magento code.
