Configuring Data Sources¶
First, you need to configure the data source that you want to use. DTV can then query and obtain the data from the configured data source and model, and render informative charts on the dashboard.
Prerequisites
You need to be assigned the required asset permission and operation permission, and a menu group containing the Dashboards > Data Sources menu. If not assigned, contact the application administrator.
