Synchronisation of mobile applications based on Java 2 Micro Edition
Synchronisation of mobile applications based on Java 2 Micro Edition
Background
PDAs, organisers and programmable mobile phones have become widespread in recent years. One of the main problems is that these devices are not used on their own, but often have to synchronise their data with databases, WWW pages or other stationary and mobile computers. There are already niche solutions for various application scenarios which, for example, only synchronise in one direction.
Just as for data synchronisation with other mobile devices, there are various physical protocols such as IrDA, Bloototh, WLAN or UTML as well as various protocols at higher levels: PalmOS, WindowsCE and SymbianOS all use their own proprietary protocols, which are incompatible with each other. SyncML is intended to replace these different protocols and thus standardise the exchange of data between devices from different manufacturers with different applications.
Job description
The following questions will be analysed on the basis of some sample applications:
- How are current PDAs and mobile phones equipped?
- What communication and, in particular, synchronisation options do these devices offer?
- How can such devices be programmed effectively?
These questions will be examined using two example applications to be programmed: canteen meal plan and grade management.
