# Operations / Areas

Data Stream supports operations, and areas. This parent child relationship combined with a sequence order creates the foundation for routing.

{% hint style="info" %}
Operations are defined as a group of process steps. 
{% endhint %}

{% hint style="info" %}
Areas are defined as the physical area these process steps are performed at.
{% endhint %}

{% hint style="success" %}
At least one operation and one area are required for routing.
{% endhint %}
