1. Provide assessment tools for the source database, enabling the capture of database statements and supporting the playback of load conditions. This enhances the compatibility of the innovation platform with the source platform. On the other hand, through the intermediate layer, necessary rewriting is achieved, automatically completing the incompatible transformation.

2. Provide a lightweight implementation based on the middle layer. On the application side, no or only a few code modifications are required to complete the dual write of data, enabling the data to be synchronously written to heterogeneous platforms. When one platform fails, it should be able to automatically degrade without affecting the normal operation of the other platform.
