prisma

Prisma schema design involves defining models, relationships, and field types that map to your database tables. Structure your schema with clear relationships (one-to-many, many-to-many), appropriate field constraints, and indexes for frequently queried columns. This foundation enables reliable CRUD operations and optimized query performance across your application.

Query optimization in Prisma includes using cursor-based pagination, selecting only required fields, and leveraging relations strategically to avoid N+1 problems. Pagination with cursor-based approaches improves performance for large datasets by fetching predictable result sets efficiently without calculating offsets.

Prisma transactions group multiple database operations into atomic units, rolling back all changes if any operation fails. Use `$transaction()` to wrap dependent queries, ensuring data consistency when performing multi-step updates or complex CRUD workflows across related records.

Prisma supports both PostgreSQL and MySQL through its connector system. Both databases are fully supported for schema design, migrations, and CRUD operations, allowing you to choose based on your infrastructure requirements without changing application code.

Prisma integrates with Node.js frameworks through client instantiation and connection pooling configuration. Configure your schema for your chosen framework, manage migrations in deployment pipelines, and use best practices for error handling and performance monitoring to ensure reliable production data access.
