Deep Dive: Domain-Driven Design
Explore advanced Domain-Driven Design concepts like event storming, context mapping, and aggregate design. This course helps you master complex systems architecture for scalable applications.
About This Course
Domain-driven design (or DDD for short) is one of the most popular software design
approaches and for excellent reason. It allows us to build highly maintainable systems
using domain-specific expertise and base our implementation on well-developed models
using ubiquitous language. In this course, Amichai Mantinband will expand on his existing
Getting Started course knowledge and dive deeper into advanced DDD concepts such as
event storming, sub-domains, bounded contexts, context mapping, aggregate design and
more. Join Amichai in this 6-hour course and get ahead of the curve on your DDD journey.
