CSC 472 Introduction to Database Systems Project Please provide answer to second question; first question is provided for reference. We have a database file with six million pages (6,000,000 pages), and we want to sort it using external merge sort. Assume that the DBMS is not using double buffering or blocked I/O, and that it uses quicksort for in-memory sorting. Assume that the DBMS has six buffers. How many runs will you produce in the second pass (Pass #1)? Group of answer choices 1,000,000 200,000 1,000,001 200,001 3,334 Refer to the previous question. How many passes does the DBMS need to perform in order to sort the file completely? (Note: an online log calculator can be found at https://www.calculator.net/log-calculator.html (Links to an external site.)) Group of answer choices 6 11 12 13 10
