# Datastores

This section provides the datastore definitions in Atoti ISDA-SIMM. The following content is included:

* A table of fields for each store within the Global datastore definition.
* Indicator showing whether the fields are KEY, VECTOR, or NULLABLE
* A column called Cube Field with "Y" or "N" value to indicate whether or not the datastore field is selected for the cube.
  * If Y: A link is also provided to the relevant level in the associated cube (i.e. the location within the cube that is populated by the value from the datastore field)
  * If N: This means the fields are either internal or measures, and there is a note to explain the details
