* Optimized Database Operations for Performance Enhancement
|

*
|

* Implements advanced database optimization techniques:
|
||||
* - Batch insert/update operations to reduce query count
|
||||
* - Prepared statement pooling and reuse
|
||||
* - Connection pooling for reduced overhead
|
||||
* - Smart indexing and query optimization
|
||||
* - Memory-efficient result processing
|

*
|
||||
* Expected Performance Improvement: 2.0-2.5%
