Embodiment Construction
[0028] Next, the present invention further illustrates how to realize data synchronization of heterogeneous databases through specific embodiments.
[0029] First, the specific principles of the embodiments of the present invention are described.
[0030] All database systems support some standard database access interfaces (ODBC, JDBC, OLEDB, etc.), and the real-time synchronization technology based on heterogeneous databases uses these standard interfaces. Taking the JDBC interface as an example, the basic principle is: suppose there are heterogeneous databases A and B, A is the database used by the user application, the database access interface uses JDBC, and B is the target database for data synchronization, it is necessary to develop a JDBC driver AB that conforms to the SUN specification, which includes the JDBC driver package of A and the JDBC of B Driver package; In terms of implementation, the user’s function calls on the AB driver are passed to the JDBC driver of th...
