To design a relational database schema that scales, apply normalization to minimize data redundancy, choose appropriate primary keys, and configure foreign keys with safe ON DELETE semantics to prevent update anomalies and maintain data integrity.

The best way to choose primary keys and timestamp strategies involves evaluating UUID versus auto-increment for uniqueness and indexing performance, while implementing created_at, updated_at, and deleted_at columns to track record lifecycle accurately.

To configure foreign keys and indexing for relationships, define ON DELETE behaviors to handle cascading removals safely, and apply indexing recommendations on foreign key columns to optimize query performance across one-to-many and many-to-many joins.

Yes, this database design guidance works for serverless PostgreSQL environments like Neon and Turso, covering indexing considerations and schema validation specifically tailored to optimize data integrity and performance in serverless deployments.

You should normalize your database schema to minimize redundancy and update anomalies in transactional applications, whereas denormalizing may be applied strategically for reporting databases to optimize complex read-heavy query performance.
