Which Tableau component allows for live data usage or scheduled updates of data extracts?

The Data Server is the component in Tableau that facilitates both live data connections and scheduled updates for data extracts. It acts as a central location for managing data sources that can be shared among various Tableau workbooks. This functionality allows users to maintain real-time data access while ensuring that updated information is available to all users in a consistent manner.

When working with live connections, the Data Server enables direct interaction with the underlying data source, allowing for immediate updates as changes occur in the data. For data extracts, it manages the scheduling of refreshes, ensuring that users always have access to the most current data without needing to manually refresh extracts.

This capability of the Data Server is essential for maintaining effective data governance and maximizing productivity, as it ensures that all users are working with the latest data without significant delays or manual intervention.
