This document provides an overview and agenda for a presentation on Domain-Driven Design (DDD) and frameworks. The presentation introduces DDD concepts and techniques like ubiquitous language, bounded context, and building blocks. It also discusses advanced DDD topics and examples. Architecture styles like layered architecture and CQRS are explained. Finally, it outlines .NET frameworks like NCQRS and Apworks that support DDD and demonstrates Apworks.

1. An introduction to DDD and Frameworks

2. Agenda
 Overview
 DDD Basis (UL, Entity, AR, VO, Services, Repositories,
Factories)
 DDD Advanced (Techniques, Anticorruption)
 Domain Model Examples
 DDD Architecture Styles (Layered, CQRS)
 Frameworks (NCQRS, Apworks)
 Apworks Demonstration
 References

3. Overview
 DDD is an approach to develop software for complex
needs
 Placing the primary focus on the core domain & its
logic
 Basing complex designs on a model
 Initiating a creative collaboration between technical
and domain experts on the heart of the problem
 Not a technology or a methodology
 More than Model-Driven Architecture

4. DDD Basis
 Ubiquitous Language
 More like a Domain Specific Language (DSL)
 Unified Modeling Language (UML)
 Bounded Context
 Context Map
 Building Blocks of DDD
 Entity
 Value Object
 Aggregate and its roots
 Domain Service
 Repository
 Specification
 Factory

5. DDD Advanced
 Technical concepts supporting DDD
 Plain Old CLR Objects (POCO)
 Inversion of Control/Dependency Injection (IoC/DI)
 Aspect-Oriented Programming (AOP)
 Domain Specific Languages
 Event Driven Architecture (CQRS Architectural Pattern)
 Anticorruption Layer

6. Domain Model Examples (Flight)

7. Domain Model Examples (Sales)

8. DDD Architectural Styles
 Layered Architecture

9. DDD Architectural Styles
 Command-Query Responsibility Segregation (CQRS)

10. Frameworks
 NCQRS (.NET)
 Axon Framework (Java)
 Jdon Framework (Java)
 Apworks (.NET)
 Supports both Layered and CQRS architecture
application development
 Visual Studio 2010/2012 Project Templates supported
 Flexible configured, any 3rd party components from
different vendors are supported to use for any purpose

11. Apworks Demonstration
 Creating Layered Applications with VS Project
Templates
 CQRS demonstration
