Which feature in Power BI helps in monitoring data and notifying users of significant changes?

The feature in Power BI that assists in monitoring data and notifying users of significant changes is alerts. Alerts allow users to set conditions on their data, and when the data meets these predefined criteria, the users receive notifications. This is particularly useful for keeping track of key performance indicators (KPIs) or important metrics. By using alerts, users can be immediately informed of critical data changes without needing to constantly check dashboards or reports.

Dashboards provide a visual representation of the most important metrics and trends, but they do not actively monitor data or send notifications. Reports deliver detailed insights and analysis but also lack the proactive notification capabilities. Datasets are the underlying data structures that contain the information used in reports and dashboards, but they do not offer any monitoring or alert functionalities. Thus, alerts stand out as the dedicated feature designed specifically for monitoring and notifying users of significant changes in data.
