Technical realization of an intelligent risk control system
DbRheo-CLI's built-in multi-level risk assessment system provides professional-grade security for database operations. The system uses a combination of static analysis and dynamic detection to evaluate the security of all modification class operations (UPDATE/DELETE/DROP, etc.) before execution.
The main protection mechanisms include: 1) syntax layer checking to identify dangerous patterns such as batch deletion without WHERE condition; 2) impact range prediction to estimate the number of rows of data that will be affected by the operation; 3) important table protection to mark business-critical tables as protected; and 4) operation history tracking to record the most recent modification operation for rollback. When a potential risk is detected, the system will pause execution and give a clear warning message, requiring the user to confirm it twice.
Typical protection scenarios such as: when a user requests to "delete test user data", the tool will first display "This operation will affect 852 records, confirm to continue?". When the high-risk command "DROP TABLE customers" is detected, the tool will force interrupt and prompt "This operation is blocked and the customers table is marked as protected".
Practice has proven that this feature can prevent more than 90% data misoperation accidents, especially suitable for use in development environments and production database maintenance scenarios, is a powerful protection tool for database administrators.
