2.1. Architecture Principles¶
The architecture principles and conventions defined in Helix focus largely on macro architecture, i.e. how the complete solution is put together for maximum productivity, quality and longevity. This is not to say that lower level architecture and principles – class design, code structure, naming conventions etc. – are not important, but these principles are often more focused on general developer practices and less related to Sitecore.
There are three main topics important to Helix and modular architecture:
- Dependencies
- which describe how feature and functionality in the solution relate to each other.
- Layers
- which control the direction of dependencies and thereby assure a manageable solution.
- Modules
- which define the isolation of features and functionality leading to greater discoverability and simplicity in the development process.
