15. Separation of Concerns | Andy Fawcett

separation of concerns

Separation of Concerns is a principle that all software engineer needs to learn. In his book, Force.com Enterprise Architecture, Andy Fawcett talks a lot about this principle and illustrates how to use it in the Salesforce solution. Hopefully it is useful for you to listen to our discussion :).

Xi’s presentation on Separation of Concerns

This is a presentation that I made in Helsinki Developer Group Meetup before recording this episode with Andy. But I think it still adds value to people who need some examples to better grab this principle.

Hope you enjoy it!
