# Calculations

export const coreProductName = "Atoti Server";

This section describes the data manipulation and calculations applied to the sensitivities from the input files.

First, the [ETL](./etl) (Extract, Transform, Load) layer will apply some transformations
as the data is loaded from the input files into the datastore.

Once the data is loaded into the datastore, it is available in the cube.
The Notional, Market Value, and JTD values in the cube may be partially aggregated upon commit to the datastore for BITMAP and LEAF aggregate providers.
The remainder of the aggregation is performed by {coreProductName} at query time.

Then, also at query time, the post-processors [calculate](./query-time-core) the capital requirements from these aggregated values.
