Methods, systems, and computer-readable medium storing instructions thereon for implementing methods are directed to facilitating data exchange, such as accessing and operating on data objects, between field applications, such as mobile clients, and dedicated servers by leveraging the features of middleware. An embodiment includes a first server providing a first set of services and data to a mobile client. A first communicating middleware is connected between the first server and the mobile client according to a first communication functionality. A second server provides a second set of services and data according to a second communication functionality that is different from the first communication functionality. A second middleware communicates with the second server according to the second communication functionality, and communicates with the first middleware according to the first communication functionality. The second middleware is connected to the second server and the first middleware.
