Step-by-step configuration guides for Prisma ORM across PostgreSQL, MySQL, SQLite, MongoDB, SQL Server, CockroachDB, and Prisma Postgres.

• Covers datasource configuration, driver adapter selection, and Prisma Client instantiation for seven database providers
• Prisma v7 requires explicit driver adapters (e.g., @prisma/adapter-pg for PostgreSQL) and a prisma.config.ts file for connection URLs
• Includes quick-reference schema blocks and prerequisite checks (Node.js 20.19.0+, TypeScript 5.4.0+)
• MongoDB support limited to Prisma v6; v7 users must upgrade or use an alternative provider
• Provides troubleshooting guidance for connection strings, environment variables, and database-specific feature setup
