Synchronization Method for specific data of DBMS mounted in embedded terminal device

摘要

Disclosed is a specific data synchronization method of a DBMS mounted in an embedded terminal. The specific data synchronization method of the DBMS is a method of synchronizing some of the records constituting a table of a DBMS mounted on an embedded terminal with new data stored in a removable storage device. Selecting at least one synchronization target record for the target; Comparing the new data with the selected synchronization target record; And synchronizing data in the table with the new data according to the comparison result. According to the present invention, data synchronization is performed only for records corresponding to data stored in the removable memory, thereby shortening the data update time of the DBMS and greatly improving the system performance of the DBMS. In addition, even if several types of data are stored in a table of a DBMS and only a specific type of data is stored in a removable memory, it is convenient to select a specific record and perform data synchronization.
