# Data Retrieval Nodes

> Learn how to use data retrieval nodes in the YiDA workbench, including methods and considerations for single-record and multi-record retrieval nodes.

Data nodes are the core feature of Integration & Automation. They operate on app-generated data to produce different execution results. Data retrieval nodes fall into two types: single-record retrieval nodes and multi-record retrieval nodes. This article explains how to use them.

## Single-Record Retrieval Node

1. Sign in to the YiDA workbench and click **My Apps**.

2. Select the app you need and go to the **App Settings** page.

3. Click **Integration & Automation**, select an existing integration & automation flow, and click **Edit**.

4. Move the cursor to the connection line of an approval node. A **+** button appears. Click **+** and select the **Get Single Record** node.

5. Select a data retrieval method. Data can be retrieved from the following sources.

<Steps>
  <Step title="Configure data filter conditions. You can select all data or filter by conditions." />

  <Step title="Configure sorting rules.">
    <Note>
      If multiple records match, the first record after filtering is returned based on the sorting rules.
    </Note>
  </Step>
</Steps>

Three options are supported: ascending, descending, and no sorting.

8. When configuration is complete, click **Save**.

## Multi-Record Retrieval Node

The multi-record retrieval node works much like the single-record retrieval node. The only difference is that a single-record retrieval node returns just one record, while a multi-record retrieval node returns multiple records.

## Notes

Keep the following in mind when using data retrieval nodes:

* If a single-record retrieval node matches multiple records, the first record after filtering is returned based on the configured sorting rules.
* A multi-record retrieval node can retrieve up to 2,000 records at a time. (The Dedicated edition supports up to 2,000 records per retrieval; other editions support up to 100.)
