Aggregate type
<programming> A data
type composed of multiple elements.
An aggregate can be homogeneous (all elements have the same type) e.g. an
array, a list in a
functional language, a string of characters, a file; or it can be heterogeneous (elements can have different types) e.g. a structure.
In most languages aggregates can contain elements which are themselves aggregates. e.g. a list of lists.
