Overview

Want to build better business software by aligning your code with your culture? Join DDD expert and business software artist Marco Heimeshoff for this intensive workshop exploring the technical relationship between code, culture and architecture and learn how to model and implement software from a business perspective.


Domain Models in Practice: DDD, CQRS & Event Sourcing with Marco Heimeshoff

You will learn how to scale your application so that any number of queries can be handled, while also maintaining a behaviour rich domain model that can deal with complex scenarios. Discover how Event Sourcing enables you to build highly cohesive and decoupled modules and changes the way you write and communicate about tests forever.

These patterns will help you to put your energy where the business value is, by letting you partition your team by their expertise and outsource the busy work. Drawing from Domain-driven design concepts, write code with Command Query Response Segregation and learn how Event Sourcing tells a story in domain terms.

Keep your software system design in line with your organisation's needs, improve readability, and strengthen your communication with key stakeholders.
