A Data Synchronization Mechanism for Cache on Mobile Client
Shun-Yan Wang, Luo Zhong, Yong-Liang Cao · 2006
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 maintenance and that of the synchronization between mobile client and server were relatively independent of each other i.e. rarely where the two were combined for putting into practice. This article combines these two kinds of key techniques organically. It proposes that every data item entering the cache has priority property and data type property, and proceeds data collection under a consistent state and also updates, replaces the cache according to the result set 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
