Final answer:
The DBMS maintains data buffers in the buffer pool, which is part of the main memory, to improve database operation efficiency by reducing disk I/O operations.
Step-by-step explanation:
The DBMS will maintain in the buffer pool, also known as the buffer cache, a number of data buffers in main memory. These data buffers are used to temporarily store data that is frequently accessed or data that has been recently read from the disk, to improve the performance and efficiency of database operations. Leveraging the speed of RAM, the DBMS minimizes the number of disk I/O operations necessary by keeping this recently accessed data in the buffers, as disk operations are significantly slower compared to memory operations.
