Explain Why The Allocation Of Records To Blocks Affects Database-syst

1.	Explain Why The Allocation Of Records To Blocks Affects Database-system Performance Significantly?
Answer» If we allocate related records to blocks, we can often retrieve most, or all, of the requested records by a query with one disk access. Disk ACCESSES TEND to be the bottlenecks in databases; since this allocation strategy reduces the number of disk accesses for a GIVEN OPERATION, it significantly IMPROVES performance. If we allocate related records to blocks, we can often retrieve most, or all, of the requested records by a query with one disk access. Disk accesses tend to be the bottlenecks in databases; since this allocation strategy reduces the number of disk accesses for a given operation, it significantly improves performance.
