Research and implementation of heterogeneous data sharing

For the heterogeneous database management system, the common method is used the XML document as the virtual Intermediary when realizing the information sharing. The disadvantage of this method is that the data is limited, the details of the implementation is complicated, and the information security is too low. By researching the Caché database technology, designed a new database management system to solve this problem. By testing the system, the performance is stable, it improved the efficiency of the data access, and the information security.
