Approaches for Core Domain/Business applications

S.O.L.I.D. principles.

Patterns of Enterprise Applications Architecture.

Martin Fowler.

Domain-driven design (DDD).

Eric Evans, Jimmy Nilsson, Vaughn Vernon, etc.

CQRS (Command and Query Responsibility Segregation).Microsoft P&P ‘CQRS Journey,’ Greg Yound, Udi Dahan.

Event driven andEvent sourcing.

Greg Young, Martin Fowler, etc.

Decoupled architectures.

Use of Dependency Injection and IoC containersMicrosoft P&P Unity, MEF, Ninject, Castle Windsor, etc.

Behavior-driven design (BDD) and TDD.

Dan North, Chris Matts, etc.Frameworks: SpecFlow, Nspec, Cuke4Nuke, Nbehave, and MSpec.

• Single Responsibility principle.• Open/close principle.• Liskov substitution principle.• Interface segregation principle.• Dependency Inversion principle.

Select architecture approaches technologies depending on your specific application’s priorities.

In large applications, when selecting architectural approaches, think about subsystems/bounded-contexts rather than the whole application.

Modernize your established applications with decoupled subsystems/bounded contexts.
