State Management Architecture: Normalizing Large Data Sets in Pinia

Normalize state by storing objects in an ID-indexed map rather than nested arrays to improve update performance and data consistency.

When dealing with relational data (e.g., Users, Posts, Comments), nested structures lead to duplicate data and complex updates. Architectural best practice involves 'flattening' the state. Use a library like normalizr or manual mapping so that an update to a 'User' object reflects instantly across all 'Post' components that reference that user.
