What is data-oriented programming and how does it differ from object-oriented programming?
What will be an ideal response?
In a data-oriented programming system such as the Web, the methods in the interface between components are
always the same. What is allowed to vary is the data that is passed through those methods and the semantics
of the processing that is applied to that data. In object-oriented programming, by contrast, each object can have
an interface with arbitrary methods. Client are usually (although not necessarily) programmed on the
assumption of specific processing semantics associated with those methods, complicating interoperation with
independently written objects.
