**Data Preparation** is a core feature of the YiDA low-code platform. It helps enterprise users clean, merge, and transform raw data before analysis or app use. Data Preparation uses a zero-code ETL (Extract, Transform, Load) approach to process data from YiDA apps, external databases, file-based sources, and official DingTalk data sources (including Contacts, OA, Smart HR, and Attendance). By building data-processing pipelines, it consolidates scattered data into standardized datasets that support visual analysis and data-driven decisions.

## Data Preparation Entitlement Upgrade

**Purchase an add-on package**

1. Go to **Platform management** > **Basic information** > **Premium features** > **Data Preparation**.

2. Click **Purchase**. DingTalk opens and displays the purchase order.

3. Select the value-added service type, then click **Share with Admin**.

**Use Data Preparation entitlements**

1. Go to **App settings** > **Data Factory** > **Data Preparation** > **Run rules**.

* Automatic downgrade: The system detects auto-run tasks that have not been used for three days and cancels them automatically.

2. Click **Settings**. In the dialog, choose a run frequency: every 1 hour, every 4 hours, or every 24 hours.
