Reducing Complexity: Replacing Entity-Based Services and Repositories with Purposeful Layers in Software Design

Short summary

Entity-based Services and Repositories have become template architecture in most projects, but this reflexive pattern often creates indirection without abstraction—empty delegates that add cognitive load without value. The solution: design layers around intent and complexity isolation, not structure. Eliminate any layer that doesn't isolate meaningful complexity; use ORMs directly when appropriate.

• •Entity-based Services/Repositories pattern widely copied but often misapplied, creating boilerplate without real architectural value
• •Layers justify their existence only when they isolate complexity; otherwise they add indirection without abstraction
• •Design around intent (e.g., 'RegisterNewUser' class) rather than structure (e.g., 'UserService'), and eliminate layers that don't pull their weight
