Reducing Software Complexity: Replacing Entity-Based Services and Repositories with Simpler Alternat
Introduction: The Entity-Based Paradigm
In the world of software development, the entity-based Services and Repositories pattern has become a default architectural choice. Every day, I encounter projects structured around layers like UserService, UserRepository, OrderService, and OrderRepository. While layering itself isn’t the issue, the mechanism of rote application is. Teams often fall into the trap of over-reliance on structural templates, creating layers without considering whether they align with the system’s intent. This is driven by environmental constraints such as time pressure, framework enforcement, and tutorial-driven practices, which prioritize speed and familiarity over optimal design.
Theoretical Intent vs. Practical Reality
In theory, a Service should encapsulate meaningful application behavior—interactions with external systems, complex business logic, or significant use cases. Similarly, a Repository should handle non-trivial data access, such as managing multiple data sources or evolving storage mechanisms. However, in practice, these layers often degrade into simple delegation or...
