# Customising the Datastore with the Datastore Helper

The Datastore Helper is a library and API, pre-configured in Atoti Market Risk, for customizing the datastore outside the standard datastore config class.

## Performing customizations

The MR libraries include implementations of the
required classes, such as `com.activeviam.mr.sensi.datastore.description.complete.stores.TradeSensitivitiesStoreConfig`.

All datastores defined in the MR libraries can be customized through the Datastore Helper.

## Examples

For details and examples of the project customizations available with
the Datastore Helper, see the [Datastore Helper
Documentation](https://docs.activeviam.com/products/tools/dash/3.4.0-AS6.1/online-help/customising-schema-with-configurator.).
