Abstract


When mobile computing age comes, demand for embedded operating system to mobile database system opens up a new field in database technology. At present, technology in embedded database system has developed from research stage into application. As mobile terminal becomes widespread, real-time process and management in this area enables embedded database system to turn out to be more powerful.This paper explains the functions, performance, and structure of the embedded database system. Its implementation is analyzed. And the key techniques of the embedded database system are pinpointed.First of all, the basic function of the embedded database system is implemented.Secondly, the key techniques of the embedded database system in this experiment, such as memorizer management, query management and data synchronization replication, are further researched. The massive materials consult, the analysis and the research had been carried on and the key effects on the performance of the system had been discovered: (1) numbers of I/O of external storage; (2) numbers of repetition of parse SQL. Through the analysis and the research on the questions above, this paper proposes and testifies the effective solutions on basis of experiment.Some techniques in this experiment, such as high-activeness data field technology and Virtual page technology, proves to be more efficient in the system. Meanwhile, other techniques, like word analysis, parsing, and pretreatment technology are discussed in this paper and a real-time synchronization method is presented.
