Data sources

A data source determines how Prisma ORM connects to your database, and is represented by the datasource block in the Prisma schema. Connection details (such as the database URL) are configured in Prisma Config. The following data source uses the postgresql provider:

datasource db {
  provider = "postgresql"
}

A Prisma schema can only have one data source. However, you can:

• Override the database connection when creating your PrismaClient
• Specify a different database for Prisma Migrate's shadow database if you are working with cloud-hosted development databases

Securing database connections

Some data source providers allow you to configure your connection with SSL/TLS by specifying certificate locations in your connection configuration.

• Configuring an SSL connection with PostgreSQL
• Configuring an SSL connection with MySQL
• Configure a TLS connection with Microsoft SQL Server

See the database-specific documentation above for examples of SSL/TLS connection configuration in Prisma Config.
