Associative array data type

An associative array data type is a data type used to represent a generalized array with no predefined cardinality. Associative arrays contain an ordered set of zero or more elements of the same data type, where each element is ordered by and can be referenced by an index value.

The index values of associative arrays are unique, are of the same data type, and do not have to be contiguous.
