VaughnVernon/IDDD_Samples
IDDD Samples
This project is a reference implementation of domain-driven design patterns and a sample of command query responsibility segregation. It provides a collection of event-driven microservices that demonstrate the practical application of architectural principles for structuring complex software systems.
The implementation separates read and write models through an event journal and organizes services into bounded contexts to maintain clear functional boundaries. It coordinates business logic by dispatching and consuming domain events to synchronize different modules.
The project covers a range of architectural capabilities, including event-sourced state persistence, materialized read projections, and domain-driven layering. It also includes a REST API implementation to expose core business logic to external systems.
Features
- Domain-Driven Designs - Provides a reference implementation of domain-driven design patterns for structuring complex software systems.
- CQRS Patterns - Splits the application into distinct write models for commands and read models for optimized querying.
- Domain Driven Design Samples - Serves as a reference sample demonstrating practical application of DDD, CQRS, and event sourcing.
- Command Query Responsibility Segregation - Demonstrates the separation of command and query responsibilities via an event journal.
- Integrated Event Storage and Streaming - Combines event sourcing and CQRS to optimize data storage and ensure consistency across distributed services.
- Event Sourcing - Persists entity state as an immutable sequence of events in an event journal.
- Bounded Contexts - Organizes services into bounded contexts to maintain clear functional boundaries and a consistent domain language.
- Read Model Projections - Pre-calculates read-only data views by subscribing to and processing domain event streams.
- Event Notifications - Dispatches domain events to keep different business modules synchronized across the system.
- Asynchronous Event Dispatchers - Implements an internal bus for publishing and dispatching domain events across decoupled modules.
- Event-Driven Coordination - Coordinates interactions between decoupled microservices using a structured event-driven architecture.
- Domain Data Presentation Layers - Separates technical infrastructure and API concerns from core business logic through domain-driven layering.
- Event-Driven Integration Platforms - Uses event-driven integration to coordinate business logic across distributed microservices.
