Engineering Contradiction Analysis
1Productivity
If multiple operations are performed simultaneously in a multi-tenant database system, then productivity is improved, but data corruption may occur due to interference between operations
Solution Approach 1:
The patent segments operations into distinct phases: simulation phase and execution phase. During simulation, operations are executed in a controlled environment with virtual locking mechanisms. During execution, the same operations are performed against actual database tables with proper locking. This segmentation allows parallel operation execution while maintaining data integrity through isolated testing and controlled deployment.
Solution Approach 2:
The patent implements preliminary simulation of operations before actual execution. The simulation phase prepares and validates operations in advance, allowing the system to identify potential conflicts and locking issues before they affect actual data. This preliminary action enables safe parallel execution by pre-resolving potential interference problems.
2Ease of manufacture
If traditional operation performance techniques are used, then device complexity is reduced, but manufacturing precision (operation correctness) cannot be verified
Solution Approach 1:
The patent creates a copy of the operation execution environment through simulation. A virtual representation of the database system and operations is maintained, allowing identical operations to be tested in isolation. This copy enables verification of operation correctness without adding significant complexity to the actual production system, as the simulation layer operates independently but mirrors the real system's behavior.
Solution Approach 2:
The patent implements feedback mechanisms that compare simulation results with actual execution results. After operations are executed against real data, the system compares the outcomes with expected results from simulation. This feedback loop verifies operation correctness automatically, providing manufacturing precision without requiring complex manual verification processes.
3Reliability
If operations are executed sequentially to prevent data corruption, then reliability is maintained, but productivity decreases due to mutual exclusion
Solution Approach 1:
The patent introduces dynamic locking mechanisms that adapt to operation requirements. Instead of fixed sequential execution, the system dynamically manages locks during simulation and execution phases. Locks are acquired and released based on actual operation needs, allowing parallel execution when safe and sequential execution only when necessary to prevent corruption. This dynamic approach maximizes both productivity and reliability.
