The student dаtа file(fixed length recоrd) cоntаins the fоllowing attributes: Id : Varchar(10) (10 bytes) Name : Varchar(10) (10 bytes) Phone : Varchar(10) (10 bytes) GPA : Double (5 bytes) -all GPAs are not null values. And index file(fixed length record) contains the following attributes: Id : Varchar(13) (13 bytes) Pointer: Double (2 bytes) There are 100,000 records in this data file. We want to store the data and index files in a hard drive with the block(page) size = 5KB ~ 5,000 B. The number of blocks or pages that need for storing the data file in a hard drive = _______ .
