Evolution of JD Advertising System Architecture: From Simple Code to Domain‑Driven Design

This article chronicles the multi‑generation architectural evolution of JD's advertising platform, explaining why a good code architecture must be extensible, reusable, maintainable and stable, and describing how domain‑driven design, aggregates, and ability orchestration were introduced to solve the challenges of complex, multi‑scenario business requirements.

Understanding Business Complexity and the Value of Domain‑Driven Design

This article explains how business complexity arises from scale and domain logic, and demonstrates how Domain‑Driven Design—through subdomains, bounded contexts, orthogonal business‑technology separation, consistent code models, and strategic‑tactical design—helps manage and reduce that complexity in software systems.

Understanding Domain-Driven Design: Core Concepts, Layers, and Patterns

This article explains the fundamentals of Domain‑Driven Design, covering the importance of a correct domain model, the layered architecture (presentation, application, domain, infrastructure), building blocks such as entities, value objects, services, aggregates, repositories, factories, and advanced topics like CQRS, Event Sourcing, Unit of Work, DCI, and the four‑color archetype analysis.

Understanding Domain-Driven Design: Core Concepts, Layers, and Patterns

This article explains the fundamentals of Domain-Driven Design, describing how a shared ubiquitous language and a well‑crafted domain model drive software architecture across presentation, application, domain, and infrastructure layers, and it covers key patterns such as aggregates, entities, value objects, repositories, CQRS, Event Sourcing, and DCI.

Understanding Aggregates, Entities, and Value Objects in Domain-Driven Design

The article explains DDD’s core building blocks—entities identified by persistent IDs, immutable value objects, and aggregates that group related objects under a single root—using a car‑model case study to show how roots enforce invariants, how factories, repositories and lazy‑loaded references fit within a hexagonal architecture, and why these practices improve modular, maintainable software.
