Child resources are resources that were created from another resource. For example, when a forecast is generated from a predictor, the forecast is the child resource and the predictor is the parent resource.

Amazon Forecast resources possess the following parent-child resource hierarchies:
+  **Dataset**: dataset import jobs
+  **Dataset Group**: predictors, predictor backtest export jobs, forecasts, forecast export jobs
+  **Predictor**: predictor backtest export jobs, forecasts, forecast export jobs
+  **Forecast**: forecast export jobs

**Note**  
 `DeleteResourceTree` will only delete Amazon Forecast resources, and will not delete datasets or exported files stored in Amazon S3.
