Abstract: A request originating at a frontend server for data encapsulated in a plurality of business objects is received. The plurality of business objects are stored in a business object layer at the backend server remote from the frontend server. In addition, the request originates from a user interface layer is received at a controller layer. A controller object is instantiated in the controller layer at the backend server. Nodes of the controller object are mapped to nodes in the plurality of business objects so that the controller object encapsulates the request data. Thereafter, transmission of data response to the request encapsulated by the controller object to the frontend server is initiated. Related apparatus, systems, techniques and articles are also described.

Abstract: A method and system are provided for communicating between two heterogeneous systems in an enterprise services architecture. A software object on a first system is associated with a node, a node attribute, an action, and a query. The software object is then formatted, or converted, into a generic version of the software object before contact with a user interface of a second system. The contact with the user interface of the second system is then made.
