What problem does it solve?

Practical guidance for applying Domain-Driven Design patterns in Jakarta EE web applications to reduce cognitive load and improve maintainability across controllers, services, entities, and DTOs.

Core Features & Use Cases

• 100% Cohesive Controllers: ensure each controller uses all injected dependencies.
• Rich Entities: embed business logic inside entities to enforce invariants.
• Form Value Objects: smart DTOs that convert themselves to domain objects.
• Domain Service Controllers: when necessary, merge controller and service responsibilities for small, clear flows.
• Load Distribution Guidance: techniques to balance cognitive load across layers in web apps.

Quick Start

Identify core domain concepts, design cohesive layers (controllers, services, entities, DTOs), then apply the load-distribution guidelines to iterate toward balanced architectures.
