4. Rethinking the extensions framework in Magento
• Efficient, secure, easy to use
• Focus: Upgradability and Compatibility
• We are introducing new concepts and gathering feedback to
refine the ideas

6. Services
• Encapsulates the access to the business logic
• Provides access to the data needed in templates
• Have well defined interfaces, which allows exposing the
logic via API
• Keeps access to business logic consistent for all clients:
SOAP, internal, etc

8. Twig templates
• Template is populated with data
• Restricts view layer from complex business logic and data
access scenarios
• Focused on data rendering
• Development of templates become easier without risk of
changing the business logic
• Allows building a secure view layer
• Automatic output encoding
• Magento provides custom functions and filters to access the
layout functionality within a template
No more SQL queries in Templates!
