Hi,
The Denodo Platform has the ability to model data types with a complex structure like registers and arrays. For arrays, find your view that contains the complex structure, create a new flatten view, and choose the array you want flattened. You can refer to [Creating Flatten Views](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_derived_views/creating_flatten_views/creating_flatten_views) in the **Virtual DataPort Administration Guide** for more information.
The function you are asking about could also describe an association which is a representation of two views and defined by two endpoints and a list of mappings. Each endpoint is associated with a view and has a 'role name', description and multiplicity. Meanwhile, a list of mappings defines the relations between the fields of the two views and allows traversing of the association. You can refer to [Associations](https://community.denodo.com/docs/html/browse/latest/en/vdp/administration/restful_architecture/associations/associations#associations) in the **Virtual DataPort Administration Guide** for more information.
Hope this helps!
