Array types are extended object-relational data-types supported by some databases. Array types are user define types in the database such as VARRAY types on Oracle. Arrays can contains basic types (VARCHAR) or other Struct types, and can be stored in a column or in a Struct type.
This annotation can be defined on a collection attribute that is persisted to an Array type. The collection can be of basic types, or embeddable class mapped using a Struct.
