Abstract
In a computer database synchronization method, a first database with first object data and a second database with second object data are established in a personal computer and an electronic dictionary, respectively. First and second synchronization status tables are established for each of the first and second object data, respectively. The synchronization status tables are modified from a first state, indicating that the corresponding object data is synchronized with the first or second database, to a second state, indicating that the corresponding object data is not synchronized with the first or second database, when the corresponding object data is edited. Synchronizing of the first and second databases can begin when a communications link is established between the personal computer and the electronic dictionary. During synchronizing, the personal computer retrieves the second synchronization status tables from the electronic dictionary, and compares the second synchronization status tables with the corresponding first synchronization status tables. Based on the results of the comparison, the personal computer retrieves the corresponding second object data from the electronic …
