Opis

The main idea of this Bachelor thesis is to synchronize mobile devices using aservice-oriented architecture. For this purpose a generic client framework hasbeen designed and implemented for the .Net Compact Framework andtargeting Windows Mobile 2005. It allows to display client-side cached usecase data via a GUI interpreter; within a not-always connected scenario,caching the data renders the devices more independent of service availability.J2EE with JAX-WS was used to design and implement a serivce-orientedarchitectur at the servers. This architecture provides a single synchronizationinterface for mobile devices, i.e. there is one common interface for allsynchronised use cases. Furthermore the architecture supports atomictransactions and the orchestration of diverse data services. Here transactionsare transparent to the mobile device, so an abborted connection doesntcause an abbort of the transaction.The data-synchronisation is achieved onthe bases of time-stamps (millisecond accuracy).
