Up until now, we have covered the basics of Magento's overall structure. We took a dive into the extension structure itself. As we progressed through individual extension structures, we familiarized ourselves with configuration file, Model, Block, Helper, controller classes, and a few other important concepts. We gave a brief intro to the Magento event/observer pattern, cron jobs functionality, and access lists. With this combined knowledge, we should now be ready for the next chapter, the full-blown extension.
