Early Firebase projects should avoid Firestore data models that mirror relational database design because Firestore requires denormalised, query-driven data structures that are fundamentally different from SQL schemas. Avoid using Firebase Realtime Database for new projects when Firestore provides better querying, offline support, and scalability. Do not store sensitive business logic solely in Firebase Cloud Functions without considering vendor lock-in, as Firebase's proprietary APIs make migration to custom backends costly once deeply embedded.
