Research on Heterogeneous Data Exchange Technology Based on Shadow Table

摘要

In the process of continuous development of enterprise informatization, with the expansion of old applications and the increasing of new applications, users will face the problem of data exchange between different hardware platforms, different network environments and different databases. Due to the coexistence of multiple application modes, the problems of data exchange between multiple systems are not standardized, network data sharing is not easy, data synchronization is not guaranteed, and data security is not guaranteed, which results in the phenomenon of "information island" and brings great inconvenience to users. The functions provided by traditional system software or tool software can not solve the problem of heterogeneous data exchange well. The research and implementation of a flexible, efficient, concise and transparent heterogeneous data exchange system is very necessary. This paper plans to study and implement a user configurable heterogeneous data exchange system which can shield complex interfaces between various data systems and has high security and reliability.
