Only the base type Array can store multiple pieces of information like multiple array elements. If you wish to associate several bits of information, you have to define a complex type that combines a number of independent base types and possibly other complex types. Such complex types are modeled as classes in UML.
For example, an Animal type might contain a string name, two DateTimes birth and lastFed and an integer weight. The implementation of Animal would be a class with several attributes of base type String, DateTime, and Integer.
The base type Array is an exception from the rule that base types do not have any sub-structure. Arrays allow multiple elements to be stored, but the array elements must be all of the same type. For example, an array may not contain string and integer elements, but only elements, which are of one of these types. Arrays may also contain complex types.
