Defining Relations in the Prisma Schema At the core of Prisma relations is the @relation directive, which you place on a field to signal a connection to another model. Refining Performance and Query Shape Performance in Prisma relations is largely governed by how you use include and select when fetching data.
Prisma Relations Migration Workflow: Seamlessly Transitioning Your Database Relationships
When you fetch a post with its comments included, Prisma runs a efficient join under the hood and nests the results in a way that feels natural to work with in TypeScript. These rules are declared in the relation directive and pushed to the database, meaning your safety net travels from the Prisma Client down to the schema itself.
One-to-Many Relationships In a one-to-many setup, think of a parent record sheltering many child records, such as a blog post with multiple comments. Prisma relations define how your data models connect, turning a simple schema into a powerful query engine that mirrors real-world relationships.

The Prisma Studio integration helps visualize these connections, allowing you to inspect join depths and verify that your indexes are properly aligned with your query patterns. You model this by placing a list of comments on the post type in Prisma, which is achieved by adding a comments field of type Comment[] and annotating it to describe the link.
