DDD eXchange 2011: Udi Dahan on Domain Models and Composite Applications
Domain Models and Composite Applications
In this talk, recorded at the DDD eXchange 2011, Udi Dahan explains the use of Bounded Contexts to turn previously monolithic systems into composite applications, now with multiple lean and mean domain models - a new perspective on DDD awaits.

As developers use DDD principles to build larger and richer systems, many of them run into performance and maintainability problems as their domain model grows to meet the demands of the system.

Performance problems addressed by eager fetching reappear later in other parts of the system, now requiring the use of lazy loading for the same entities.

Udi Dahan's Advanced Distributed Systems Design with SOA

This very intensive 5-day workshop will help you take the pain out of designing large-scale distributed systems. New technologies make it easier to comply with today’s communications and security standards, but they won't magically provide you with a robust and scalable system. Join Udi for a course packed with the wisdom of companies like SUN, Amazon and eBay. Tried-and-true theories and fallacies will be shown, helping you to avoid costly mistakes. Communications patterns like publish/subscribe and correlated one-way request/response will be demonstrated, in conjunction with advanced object-oriented state management practices for long-running workflows. If you enjoy deep architectural discussion, join! To find out more, please go here

DDD eXchange 2012 (June 15 2012)

The fifth DDD eXchange will take place at Skills Matter eXchange on the 15th June 2012. Find out more, follow #DDDX on Twitter and book your ticket here

Eric Evans Domain Driven Design Hands-On Immersion Workshop

Eric Evans' 4-day Domain Driven Design Hands-On Immersion Workshop will teach you how to put the domain model to work. This intensive course will teach you how to strike a healthy balance between digging into your subject matter and addressing technological issues, which, while unavoidable, cannot be allowed to dominate the development process for commercially viable systems. We weave together lecture, discussion and classroom exercises, including hands-on coding projects. In discussions, you will have the opportunity to discuss your own experiences and relate your own work to the principles and techniques presented in the class. To find out more, please go here

Greg Young's CQRS, Domain Events, Event Sourcing and how to apply DDD

This 3-day CQRS course covers Domain Events, Event Sourcing and how to apply DDD. Join to learn all about system building and architectures with Domain Driven Design. The largest problem many run into with Domain Driven Design is in getting the abstract concepts implemented in a concrete way. Many of the stereotypical architectures people use actually make it impossible to apply DDD. Greg's course will help you avoid this. To find out more, please go here

Simon Brown's software architecture for developers

This course is about broadening your software development skills and has been designed to take full advantage of the technical knowledge that you already have. Simon Brown's software architecture development course will make you more 'architecturally aware', and will help you to build better software. It's about pragmatic and real-world software architecture rather than academic "ivory tower" software architecture and is presented by Simon Brown. To find out more, please go here
