This manual is no longer being maintained for TYPO3 versions 11.5 and above. The majority of the content has been migrated to the Extbase or Fluid sections in "TYPO3 Explained".


In this chapter you have learned how to use the Model View Controller Design Pattern, which divides the applications in the data model and the user interaction, in Extbase.

Domain Driven Design and the MVC architecture form the conceptual backbone of Extbase. Additionally, we recommend a look at test driven development as a development paradigm, which lowers the probability of errors in the code dramatically and structures the daily work of developer even more.

With these base concepts you are perfectly prepared for the next chapters. Now dive into the depths of Extbase with us!
