🌟 Business Features

🛡️ Extreme Data Consistency

• Atomic Bookkeeping: When adding records, the system guarantees that the main record and balance changes are written synchronously, preventing data discrepancies.
• Reversal Logic: When modifying or deleting transactions, the system does not erase data. Instead, it executes "reversal operations" to maintain balance equilibrium, preserving a complete Audit Trail.

💸 High-Security Fund Transfers

• Linked Binding: When performing transfers, the system strictly binds outgoing and incoming records, ensuring the atomicity of both sides and preventing funds from disappearing or appearing out of thin air during movement.

📊 Professional Batch Data Processing

• Atomic Import Mechanism: Supports high-volume Excel data imports. All data enters a "Staging Area" for validation and can only be committed to production tables with one click after confirmation.
• One-Click Batch Rollback: If imported data is found to be incorrect, an atomic rollback can be executed based on a Batch ID, quickly restoring the system to its pre-import state.

📈 Modern Performance Architecture

• High Concurrency Handling: Optimized for processing large volumes of financial records. The system remains responsive even when multiple users are performing complex report imports and queries simultaneously.
