# Using Datasets
Datasets can be used in a form or in a workflow task.
When used in a form a dataset is referenced so that a read operation can be performed on that dataset. When used in a workflow task, a dataset is referenced so that an update operation can be performed on that dataset.
For both scenarios, this reference to the dataset is done via Dataset connections.
## Dataset Connection
A dataset connection is simply a reference to a dataset for purposes of a read or update operation.
### Read Dataset Connection
A read dataset connection can be done from the form either on the [configuration of a drop down field](/managing-services/managing-forms/using-the-form-builder/form-field-types.md#settings-4) or [configuration of a field validator](/managing-services/managing-forms/using-the-form-builder/field-validators.md).
To create a read dataset connection:
* Click on the add icon or edit icon next to the data connection field.
* The dataset connection form appears
* Choose reference type as 'Local' to connect to a dataset that is available on your organization's account.
* Choose the dataset you want to connect to.
* Provide a connection name.
* Click on the save button
* You can now use this connection for all other assets in your organization's account.
### Update Dataset Connection
An update dataset connection can be done from a workflow service task that is intended to [update a dataset](/managing-services/building-the-workflow/service-task-types.md#update-dataset).
To create an update dataset connection:
* Click on the add icon or edit icon next to the data connection field.
* The update dataset connection form appears
* Choose a dataset that you want to connect to
* Provide or edit the connection name
* Choose the form that will contain the source data for updating the dataset.
* Add mappings for the update. For each mapping added:
* Choose the target field to be updated on the dataset
* Choose the source field from the selected form that will update the corresponding target field on the dataset
* Note: For source fields that are of the type "dynamic matrix field", the rows in the data for the field will each be saved as a separate dataset record and you must add a mapping for each column in your dynamic matrix field.
