Hive complex data types such as arrays, maps, and structs are a composite of primitive or complex data types. Informatica Developer represents complex data types with the string data type and uses delimiters to separate the elements of the complex data type.

The following table describes the transformation types and delimiters that are used to represent the complex data types:

Complex Data Type	Description
Array	The elements in the array are of string data type. The elements in the array are delimited by commas. For example, an array of fruits is represented as [apple,banana,orange] .
Map	Maps contain key-value pairs and are represented as pairs of strings and integers delimited by the = character. String and integer pairs are delimited by commas. For example, a map of fruits is represented as [1=apple,2=banana,3=orange] .
Struct	Structs are represented as pairs of strings and integers delimited by the : character. String and integer pairs are delimited by commas. For example, a struct of fruits is represented as [1,apple] .
