# Linked Data

**In Pathways, you can link** **a data collection from the Data Manager.** This allows you to use data in a Data Activity or in Data Tracking.

## How to link data in Pathways

{% hint style="info" %}
To link data, you first need to create a Data Collection in [Data Manager](broken://pages/PFBMAGvj3EjWXaF4C1Hj).
{% endhint %}

1. **Open** [**Pathways**](https://everyday-digital.gitbook.io/pathways-docs/) **and go to Linked Data.**
2. **Select the + icon (bottom right).**
3. **Select a Data Collection that has been created in** [**Data Manager**](broken://pages/PFBMAGvj3EjWXaF4C1Hj)**.** Use the dropdown menu to make a selection.
4. **Indicate the data source type:** primary or secondary.
5. **Specify the** [**User Identifier Type**](broken://pages/PFBMAGvj3EjWXaF4C1Hj#unique-identifiers) **and the** **Corresponding Column**. This ensures that a unique identifier can be matched to a corresponding column name in your data upload. 
6. **Specify the Key Performance Indicator (KPI) column.** This allows you to track, visualise and match data in relation to goals, targets or dependencies. Data Targets can be set in a Data Activation Activity on a [Pathway](https://everyday-digital.gitbook.io/pathways-docs/).

In this example, sales are being tracked:
