enterprise, the users work remotely, which requires a mediator for
establishing communication between the mobile devices and the
enterprise system. Hence, Mobile Engine architecture concentrates on
providing secure, timely and critical business transactions over a
network.
Further to the discussion in
section 2.1, Mobile Engine architecture contains basic components,
which help in realizing mobile solutions for a SAP system. There are
two sets of components, which are differentiated on the basis of
their installation. For a successful mobile engine solution,
appropriate components should be installed at mobile device and the
