The article discusses the characteristics of mobile and embedded database as well as its synchronization realization on mobile terminal along with practical application. The article further provides several methods to improve the data accessing rate, efficiency, stability, maintainability and uniformity of the database, including multithread technology, three-layer duplication/buffer architecture,...
By studying the current mainstream database system, with message queue method mechanism and JMS messaging services, we designed a data synchronization system model. We introduced the model's major technology and work processes in detail. Finally, we analyzed the system's inadequacy and made some improvements.
Benefiting from the development of network technology, applications based on distributed system become more and more popular. In these applications, different copies of data are always stored in different databases, so the data synchronization becomes very important. Firstly, this paper analyzes existing data synchronization technology. And then it describes the architecture and the major advantages...
In the EDBMGIS (Embedded Database Based Mobile Geospatial Information Service) architecture application, the data of embedded database in the mobile terminal is duplicated from the server. After a period's system operation, data in both the mobile client and server will be changed. In order to keep the data consistency, the synchronization of data on both side is discussed in this paper. In addition,...
