Page Table is a data structure in Buffer Pool Manager that tracks page status and metadata for efficient memory management in industrial systems.
The Page Table is a critical component within the Buffer Pool Manager of industrial machinery and computing systems, serving as a centralized registry that maintains metadata for all pages currently stored in the buffer pool. It maps logical page identifiers to physical buffer frame locations, tracks page states (clean/dirty, pinned/unpinned), records access patterns, and manages page replacement policies. This component enables efficient memory allocation, reduces disk I/O operations, and optimizes system performance by providing rapid access to frequently used data pages.

The Page Table manages metadata for pages in the buffer pool, enabling efficient memory access, reducing disk operations, and optimizing system performance in industrial computing environments.
It implements algorithms like LRU or Clock to track page usage patterns and determine which pages to evict when the buffer pool reaches capacity, ensuring optimal memory utilization.
Lookup speed, memory efficiency, concurrency handling, and accuracy in tracking page states are critical performance indicators for industrial Page Table implementations.
