# Workflow step dependencies

A visual aid that provides a quick overview of the relationships between your workflow steps. 

This is a visual aid that provides a quick overview of the relationships between your workflow steps. 
There are three groups of relationships:

#### 1. Step data source and destination relationship

#### 2. Same storage key relationship

#### 3. Break-loop belonging to a certain loop relationship

####

### Examples

In the below example:

* The step 'Filter events' uses data from the trigger 'Get events'
* The data is then pumped to 'Set events in storage' and Loop events (in other words 'Set events in storage' and 'Loop events' use data from 'Filter events')

If we select another step from this workflow, 'Set events in storage', we see it uses the data from the 'Filter events' step.
Also, as a Storage step, it uses the same key as the 'Get events from storage' step (highlighted in green):

If we select another step, the 'Break Loop' step, the Loop associated with this break-loop step gets highlighted in yellow.
This means that this is the Loop that will be exited when the Break Loop step will be encountered:
