# Examples

## Connecting to MongoDB Atlas

The following steps will help you connect your Historian instance to an **Atlas Cluster** in a matter of minutes.

### Prerequisites

- An Atlas account.
- An organization and project with an account's user who has permission to create clusters.
- An active cluster created in this account.
- An IP address added to your IP access list.
- A Database user on your cluster.

Take a look at the [MongoDB Documentation](https://www.mongodb.com/docs/atlas/) for more information.

### Getting the Connection String from Atlas

You'll need to get your cluster's connection string from Atlas to connect your **N3uron's Historian instance** to the cluster using the **Node.js** driver.

**Step 1:** Click on **Connect:**

- Click on **Clusters** in the top-left corner of Atlas.
- In the **Clusters** view, click on **Connect** for the database deployment to which you want to connect.

## Connecting to TigerData

The following steps will help you connect your Historian instance to a **TigerData instance**.

### Prerequisites

- A [TigerData](https://www.tigerdata.com/) account.
- An active instance created in this account.
- An IP address added to your IP access list.

### Getting the connection details from TigerData

**Step 1:** In your Timescale project, navigate to **Overview**, then select **More details** in the **Service Info** section.

### Configuring N3uron

**Step 1:** Select **External** as the database type.

![](https://cdn.document360.io/54093ab5-6b22-4542-a265-04377931f11a/Images/Documentation/select%20external.png)

**Step 2:** Select **TimescaleDB** as the database engine.

## Connecting Historian to a self-managed MongoDB Replica Set

The following steps will help you connect the N3uron Historian to a self-managed MongoDB replica set deployment.

Example replica set with name **rs0** (refer to this [guide](https://www.mongodb.com/docs/manual/tutorial/deploy-replica-set/#overview) on deploying a replica set):

- [mongodb0.example.net:27017](//mongodb0.example.net:27017)
- [mongodb1.example.net:27017](//mongodb1.example.net:27017)
- [mongodb2.example.net:27017](//mongodb2.example.net:27017)

### Build the MongoDB connection string

This is the standard connection URI format. Refer to the [official documentation](https://www.mongodb.com/docs/manual/reference/connection-string/#standard-connection-string-format) for more details.

```plaintext
mongodb://[username:password@]host1[:port1][,...hostN[:portN]][/[defaultauthdb][?options]]
```

For the example above, the connection URL should be:

```plaintext
mongodb://username:password@mongodb0.example.net:27017,mongodb1.example.net:27017,mongodb2.example.net:27017/n3-history?replicaSet=rs0
```

### Configuring N3uron

**Step 1:** Go to the Historian module configuration and select **External** as the database type and **mongodb** as the protocol.

**Step 2:** Open the database connection helper, paste the connection URI created in the previous section, and click **Apply.**
