# Explore Data Usage

In the [Project Workshop](condition-data/project-workshop-view), all of the items in your project have a **Usage** tab, which shows the item's dependents. That is, other items (such as calculated fields, data hierarchies, data links, generated date/time fields, and tables/fields) that are making use of the item. This may be used to understand where data is being used, and the impact of changes on the current dashboard design. Note that data cannot be changed while it is being used by a chart; the chart must be disconnected before the change can be made.
