How to determine which of two databases to use based on classification results?

To understand which of the two databases to query based on the classification result, you need to:

1. Define classification criteria. For example, if the classifier determines the type of request or data category.

2. Configure routing logic. After obtaining the classification result, the system should direct the request to the appropriate database.

3. Use metadata or rules. For example, if the classification returns a label "A", query database A; if "B", query database B.

4. Ensure data consistency. It is important that data related to a specific category is stored in the corresponding database.

Example: the classifier determines that the request relates to "user data" or "logs". Then, requests for user data go to the user database, and requests for logs go to the logs database.

Thus, the classification result acts as a trigger for selecting the required database.
