(Physical Data Organization ) For this exercise, assume a sorted file with 40,000 records and a block size of 512 bytes. Each record has a fixed-length size of 200 bytes. An index entry needs 9 bytes for the index field and 6 bytes for the pointer. b) What is the number of accesses when there is no primary index but the search still refer to the primary key attribute? It is sufficient if you answer the question theoretically.
