Application Framework
Application Framework functionality is a part of OroPlatform that determines the structure of the Oro application (code organization, file structure, application flow routine) and the way of interaction between independent components in the application.
In this section, you’ll find a description of the main principles on how to organize your adjustments to Oro applications.
How It Works
Application Framework functionality in OroPlatform is based on the Symfony Framework and extends it in the OroPlatformBundle and OroDistributionBundle to improve several aspects of development experience.
Please refer to the Architecture Principles of Oro Applications article for the synopsis of structural aspects of the Oro applications:
- Symfony Role in OroPlatform
- HTTP Request Application Flow
- Event System
- Inversion of Control Principle
- Bundle System
- Application Directory Structure
- Application Configuration
- Templating System
- Security System (Data Access Management)
- Databases Management (Doctrine ORM)
- CLI Application
- List of Symfony Components Used in Oro Applications
