Design a scalable database schema by separating entities into focused tables, applying normalization to minimize redundancy, and selecting appropriate primary and foreign keys to define clear relationships for transactional apps.

Database normalization is the process of organizing data to minimize redundancy. You should split data into separate tables when it reduces anomalies and ensures clear, focused entities for scalable transactional applications.

Choose primary and foreign keys for multi-tenant isolation by selecting consistent key strategies that define clear relationships and enforce data boundaries, ensuring scalable schema evolution without data anomalies.

For robust database auditing, establish consistent timestamp conventions using created_at, updated_at, and optional deleted_at columns to track records and support reliable schema migrations.

Handle database migrations and avoid brittle schema changes by applying practical migration considerations alongside clear normalization, primary and foreign key strategies, and consistent timestamp conventions.
