This report outlines the implementation of in Golang , focusing on creating simple and maintainable systems for complex business logic. DDD aligns software code—such as package and variable names—with the business domain. Core Concepts of DDD in Go

: Focuses on "what" the system does rather than "how" it's stored, which is vital for long-term project health.

: An abstraction layer between the domain and the data store, allowing the domain to remain agnostic of the underlying database. Proposed Project Structure This report outlines the implementation of in Golang

Go's package system is well-suited for DDD. A common approach is to use the internal directory to prevent external exposure of domain-specific logic. Responsibility Typical Go Package Core business logic, entities, and repository interfaces. internal/domain Application Orchestrates tasks and delegates to domain objects. internal/application Infrastructure Implements repository interfaces (DB, APIs). internal/infrastructure Interfaces Entry points for the system (HTTP, CLI, gRPC). internal/interfaces Key Tactical Implementation Steps

DDD is divided into strategic and tactical patterns. Tactical patterns are the primary focus when structuring a Go codebase. : An abstraction layer between the domain and

: Decoupled systems allow for easier unit testing of business rules without requiring a live database.

: Ensuring that the code reflects the same terminology used by business experts (e.g., using LoanApplication instead of GenericForm ). This report outlines the implementation of in Golang

: Use Ports & Adapters (Hexagonal Architecture) alongside DDD to ensure that external technologies (like MongoDB or Postgres) do not leak into the business logic. Strategic Benefits
