Database store concepts question about blocking 

 

1. [10] La Trobe University has approximately 20,000 active students. On the average, a student data will require 500 characters. The student table is stored in Oracle Database: No Question a Block Size (Bytes) b Blocking Factor (bfr) C d Number of blocks required Total space required (Bytes) e Total used space (Bytes) f Total wasted space (Bytes) Answer 8192 Page 5 of 7 2. [10] The length of student ID is 15 Bytes. If the data is stored in ordered by the student ID, calculate the number of blocks required to obtain these data. We assume that there is only 1 level of block index. We assume that pointer size is OB.
