Q1: Given the following data file Student (NAME, ID.NO, GPA, ...) Suppose that: The file is ordered by D.NO Record size R=125 bytes Block size B=512 bytes The file contains 5000 records For an index on the D.NO field, assume the field size VD.NO=3 bytes, assume the record pointer size PR=7 bytes. CALCULATE following blocking factor Index blocking factor Bfri= Number of index blocks bi (Using Primary Index) How Many Block access needed if applying linear search On the file On Average How Many Block access needed if applying Binary search On the index file
