There are two ways to achieve database synchronization. The first one is based on the log database, will modify a database to another database application. This method of the same database, and the data structure of the same situation. If you want this synchronization method applied to different types of databases, or database data types, will encounter difficulties. The second way to achieve is to analyze the contents of two databases, find the differences, the differences will be part of the record is written each database. In this way the data type is not strictly required, because the data transfer from one database to another database before writing, you can make the appropriate type conversion. If you use the ODBC interface to access the database, such synchronization approach can also be applied in a variety of synchronization between heterogeneous databases.
