An action query performs an action on the table on which it is based. Actions include updating data in the table e. A cross-tab query performs calculations on the values in a field and displays the results in a datasheet.
The reason it is called cross-tab is that it tabulates the data for a set of descriptor attributes, contrasting them or crossing them in a table format.

Take the list of HR database common fields, and group them into tables.
