A fast concurrency control algorithm in embedded real-time database system

With the quick development of mobile communication technology and the continuous popularization of mobile computer, the embedded real time database formed by the combination of mobile computing, real time application and embedded environment has already become the emerging hot subject in the field of database system. Combing the characteristics of embedded, mobile and real-time environment and fully considering broadcast strategy, the feature and data feature of real-time database system transaction, a new set of design idea for concurrency control algorithm at clients and server, which consider the promotion of hit rate of buffer page and finish rate on time for real-time transaction as the goal, is put forward in this paper.
