Database schema design requires defining entities, keys, relationships, and explicit constraints. Planning access paths and indexing strategies ensures data integrity while supporting evolving workloads across backend services without costly rewrites.

Safe database migrations require careful planning for scalability and data integrity. You need rollout guidance for migrations, backfills, and backward compatibility to evolve systems without disrupting existing backend services.

Defining entity relationships involves specifying core entities, lifecycle rules, and ownership with explicit constraints. Clear deletion semantics prevent data inconsistencies and ensure durable schema persistence across the system.

Indexing strategies and access paths are needed when defining database persistence for new data models. Planning these access paths supports evolving workloads and ensures efficient queries across backend services.

Yes, this database design approach applies to both new data models and evolving systems. It provides rollout guidance for migrations and backfills while maintaining backward compatibility across backend services.

Explicit constraints and migration plans prevent data inconsistencies and costly rewrites. Without defining lifecycle rules and deletion semantics, evolving systems risk losing data integrity during schema changes.
