With the addition of the Categorical class, the following mapping between UNICOM Intelligence data types and JavaScript classes is possible:

UNICOM Intelligence to JavaScript mapping

UNICOM Intelligence data type	JavaScript class type

UNICOM Intelligence supports operations between data types by following defined rules. For more information, see Operators.
