Better software design with domain modeling by Eric Normand

Software design is all about making design decisions. We make better design decisions when we have more relevant information. In this talk, we will explore three perspectives from domain modeling to help you extract more information about the problem your software is trying to solve to make better software design decisions. Along the way, we will see how building the domain model in your implementation language helps you understand your domain better, why poor domain models make our code messy, and how to deal with the inevitability of change. The ideal end result is a fun, iterative, expressive, and flexible domain model.
