2. Components
Open Mobile IS connects the company information system to nomad users by a safe link between mobile terminals (PDA,PC...) and the company information system.Open Mobile IS technology leans on four essential components:

- Embedded Web server and embedded data base
The applications Server integrates the whole of the software components allowing the developpement of powerful mobile applications. It mainly integrates a client-side Web server and an embedded data base optimized for low CPU mobile devices.

Benefit :
- Applications are accessible from the terminal customer browser through a services portal.
- The application Server deals with the services and the interfaces dynamic generation,
- Storage and synchronization of the data for a disconnected use of the developed services.

The Server also integrates access API to the terminal native applications, like Microsoft Outlook, and to connections networks. It also offers a synchronization service, managing users’ synchronization requests.


Benefit :
- Availability of applications and data on both mode : connected and disconnected.
- Possibility of exploiting important Data volumes on mobile devices.


-The Synchronization engine :
The Synchronization engine allows the update of the data (client/contact, e-mails, meeting, reporting...)
with the company information system servers in a transparent way for the user.

Benefit :
- Permanent accessibility of the data : Even in the absence of connection network (GPRS, Wifi...)
- applications remain available and data exploitable.
- A single process for the whole synchronization: Data, updates and software evolutions are synchronized       simultaneously
- An optimized exchange process : Times of synchronization and exchanged data volumes are optimized by the use  of an incremental synchronization process: only modified data are updated on both Server and client side in order   to optimize communication costs and to insure synchronization duration prediction.


- The Synchronisation Server :
On the server side OpenMobile IS provide the server part of the synchronisation engine. This module use a servlet for the web server integration. Synchronisation request are validated (users' accesses and profils' accesses) and executed. Database intégration is done with JDBC driver. This module is compatible with J2EE architecture.

Benefit :
- A maximum compatibility : The Synchronization Server facilitates the accesses to the information system thanks to   its exclusive connectors towards the standards of industry.

Nota : Synchronization services are developed in JAVA.
