A Data Synchronization Mechanism for Cache on Mobile Client
Cache technology was an important technique that supported the disconnected operation between mobile clients and servers. For the time being ，the research on mobile client cache data maintaining and that of the synchronization between mobile client and server were relatively independent of each other i.e. rarely were the two been combined for putting into practice. This article combines these two kinds of key techniques organically. It proposes every data item entering cache has priority property and data type property, proceeds data collection under consistent state and also update, replace the cache according to the resultset of mobile client transaction. This article puts forward a kind of synchronous mechanism based on mobile client cache data classification, adopting different synchronous strategy for different data and so raises the efficiency of mobile database system and the success ratio of committing transient transaction.
