Simulated Data Migration for Cloud Database Quality Assurance

The patent applies preliminary action by simulating the migration process before actual data migration occurs. A simulation engine creates simulated target data from source data using the same migration rules that will be applied during actual migration. This allows validation and discrepancy detection to be performed in advance, ensuring data quality before the actual migration takes place, thus resolving the contradiction between improved data distribution and maintained data quality assurance.

The patent uses copying by creating a simulated copy of the target data through the simulation engine. This simulated target data is generated by applying the same migration rules to source data, creating an identical copy of what the actual migration will produce. By comparing this simulated copy with the actual migrated data, the system can validate accuracy and consistency without compromising the transformation capability, thus resolving the contradiction between adaptability and measurement precision.

The patent applies preliminary action by pre-processing and pre-comparing data structures before actual migration validation. The simulation engine pre-generates expected target data structures and pre-identifies potential discrepancies using machine learning algorithms. This preliminary validation reduces the time required during actual migration, as the heavy computational work of discrepancy detection is performed in advance, thus resolving the contradiction between validation accuracy and processing time.
