Based On Efficient Database Design And Embedded Systems

As the core technique of mobile-computing,mobile-commerce and informative electrical appliances, The Embedded Database Management System appears recently which is a newly data management technology.The EDBMS which based on the mature technology of DBMS and aimed at the idiographic embedded system and device,implements the embedded system data store,data organize,data management and data exchange with the background data source according practical requirement.The author took part in the development of the Simba EDBMS and then finished this thesis. The particularity and the advanced technology of the embedded system and EDBMS are introduced firstly. The author point out that the capability of EDBMS is decided by the spending of system resource but not the traditional number of I/O operation according to the peculiarity of embedded system and the appliances requirement. In the paper, the system architecture of the EDBMS based on the EMS memory is pinpointed. Those pivotal techniques in the development of the system, including the physical memorizer management,query process,data synchronization and other technology are further discussed.
