Explore core concepts of Domain Driven Design, its pros and cons, modeling techniques, and hexagonal architecture to transform complex business requirements into effective software solutions.

In this course, you are going to learn the most important concepts of Domain Driven Design or DDD for short. You will see both benefits and drawbacks, techniques to model, how DDD can be implemented using hexagonal architecture and many other amazing concepts.

By the end of this course, you will be able to take complex business requirements and processes and turn them into meaningful software.
