-Ideally, your read and write models should differ. You might want to expose less data in a
-collection view (Output DTO) or enforce strict validation during creation/updates (Input DTOs).
+For write operations, you often want different validation rules or structures for creation versus
+updates. Use dedicated input DTOs with the `#[Map(target: EntityClass::class)]` attribute to
+transform input data into your entity before persistence.

 For POST and PATCH, we define specific DTOs. The `#[Map(target: BookEntity::class)]` attribute tells
 the system to map this DTO onto the Entity class before persistence.
