Avoiding Monoliths

Hanna Kollo slides: http://harbour77.eu/?p=86

• Single big monlith is bad
• Having many very small apps all being very inter-related is also not great
• 2nd iteration was fewer larger apps, less dependencies to follow between apps
• many models in few apps
• easier to understand
• rather than putting lots of business logic in models, added a service layer
• ideas from https://stackoverflow.com/questions/12578908/separation-of-business-logic-and-data-access-in-django
• the business logic is not only about the data
• models used for reading, but update/insert always done through service layer
