Patterns, Principles and Practices of Domain-Driven Design

Domain-Driven Design (DDD) is a software development philosophy for tackling complex systems. Software is based around a model of the business domain in code to enable developers and business users to talk about problems in a single language. DDD is attracting new adoptees as .NET developers continue to mature and seek out best practices for developing enterprise level applications. This book is the first to present the philosophy of DDD in a down to earth practical manner for experienced developers. It shows developers how the concepts of DDD can be applied to their applications with real world examples. Unlike other books on the subject, it is packed with patterns, code examples and case studies that help to cement the theory of DDD. After introducing readers to DDD and its application (complete with development best practices and patterns), it goes on to explain Command, Query, Responsibility Segregation Architecture (CQRS), an architectural pattern that can be used to implement a DDD design methodology. Finally, a case study is included to show DDD, CQRS, and Messaging Pub/Sub architecture in the context of a real set of enterprise applications. The book includes:  An introduction to the philosophy of Domain-Driven Design (DDD) Command, Query, Responsibility Segregation Architecture (CQRS) DDD Best practices for modeling patterns Publish/Subscribe Messaging Architecture for Bounded Contexts  Throughout, the book gives the reader masses of code and examples of the concepts that other books have theorized about.
