An automobile part trading company would like to store the following attributes for each part in a database table: PartNo: 10 bytes Name: 30 bytes UintMeasure: 5 bytes UnitCost: 4 bytes UnitPrice: 4 byes QtyOnHand: 4 bytes QtyOnOrder: 4bytes PreferredSupplier: 30 bytes Consider a disk with block size of 512 bytes and block pointer of 6 bytes long. Each record has a unique value of PartNo. There are altogether 50,000 parts in the company. Compute the following: i) The number of file blocks required for storing the part records. ii) The percentage of disk space saving achieved by implementing PartNo as primary index from implementing it as secondary index. iii) The percentage of improvement on number of block accesses required for searching a product record based on PartNos value achieved by implementing PartNo as primary index from implementing it as secondary index.
