SAP Mobile Engine Architecture

The objective of a Mobile Engine is to provide mobility to enterprise systems. In a mobile 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 corresponding SAP system. The mobile device components include:

* Interface
o Browser based
o Native
* Local Web Server
o Servlet Engine
* Business Logic (Programming models)
o Micro ITS
o JSP
o Cached HTML pages (or offline browsing)
o Any other Customized model
* Public Interface Layer
o Synchronization Layer


In the above Figure it displays the way these components are structured to form a Mobile Engine.
