6.2.1.2.4Object Abstraction IoT relies on a vast and heterogeneous set of objects, each one of which is providing specific functions accessible through its own dialect. Thus, there is a need for anabstraction layerwhich is capable of harmonizing access to different devices with a common language...
Abstractions such as data formats and layouts typically spread multiple layers in traditional DBMS, the way they are processed is encapsulated within these layers of abstraction. The NDP-style processing requires an explicit definition of cross-layer data formats and accessors to ensure in-situ ...
