A `datasource` block accepts the following fields:

| Name | Required | Type | Description |
| ------------------- | -------- | ------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `provider` | **Yes** | String (`postgresql`, `mysql`, `sqlite`, `sqlserver`, `mongodb`, `cockroachdb`) | Describes which data source connectors to use. |
| `url` | **Yes** | String (URL) | Connection URL including authentication info. Most connectors use [the syntax provided by the database](/reference/database-reference/connection-urls#format). |
| `shadowDatabaseUrl` | No | String (URL) | Connection URL to the shadow database used by Prisma Migrate. Allows you to use a cloud-hosted database as the shadow database. |
| `directUrl` | No | String (URL) | Connection URL for [direct connection to the database](/data-platform/data-proxy/prisma-cli-with-data-proxy#set-a-direct-database-connection-url-in-your-prisma-schema).<br /><br />If you use a connection pooler URL in the `url` argument (for example, if you use the Data Proxy or pgBouncer), Prisma CLI commands [that require a direct connection to the database](/data-platform/data-proxy/prisma-cli-with-data-proxy#prisma-cli-commands-that-require-a-direct-database-connection) (such as `migrate dev` or `db pull`) use the URL in the `directUrl` argument. |
| `relationMode` | No | String (`foreignKeys`, `prisma`) | Sets whether [referential integrity](/concepts/components/prisma-schema/relations/relation-mode) is enforced by foreign keys in the database or emulated in the Prisma Client.<br /><br />In preview in versions 3.1.1 and later. The field is named `relationMode` in versions 4.5.0 and later, and was previously named `referentialIntegrity`. |
| `extensions` | No | List of strings (PostgreSQL extension names) | Allows you to [represent PostgreSQL extensions in your schema](/concepts/components/prisma-schema/postgresql-extensions#how-to-represent-postgresql-extensions-in-your-prisma-schema). Available in preview for PostgreSQL only in Prisma versions 4.5.0 and later. |

If you are using a `prisma://` URL in the `url` argument, you may use the [Data Browser](/data-platform) as an alternative to Prisma Studio. |
