SYNCHRONIZATION OF MOBILE DEVICES AND WORK IN OFF-LINE MODE

Sinhronizacija mobilne naprave s strežnikom in trajno shranjevanje podatkov na mobilni napravi nam omogoča številne prednosti in dodatne funkcionalnosti. V diplomski nalogi smo raziskali različne pristope sinhronizacije mobilne naprave s strežnikom, podrobneje smo analizirali formate podatkov, ki se izmenjujejo, ter njihove prednosti, slabosti in možnosti optimizacije. Podatke je na mobilni napravi potrebno ustrezno razčleniti, obdelati in shraniti. Raziskali smo različne načine razčlenjevanja in trajnega shranjevanja podatkov na mobilni platformi Android in mobilni aplikaciji razviti s pomočjo HTML 5 in povezanih tehnologij. Implementirali smo strežniško logiko in aplikaciji, ki uporabljajo omenjene koncepte in izvajajo meritve nad razčlenjevanjem in shranjevanjem prenesenih podatkov.Synchronization of the mobile device with the server and permanent saving of data on the mobile device provide numerous advantages and additional features. In the thesis we analyzed different approaches of synchronization of the mobile device with the server, thoroughly analyzed formal data, that is being exchanged, and their advantages, weaknesses and possibilities for optimization. The data on the mobile device needs to be thoroughly parsed, processed and saved. We analyzed different ways of parsing and permanent saving of data on the mobile platform Android and a mobile application, developed with HTML 5 and connected technologies. We implemented a server logic and applications that use the stated concepts and carry out measurements over parsing and saving of the transferred data
