Assume a relation ‘R’ having 200 records. These records are stored in blocks having block factor as 20. Consider another relation ‘S’ having 120 records and all these records are stored in 30 blocks. These two tables have to be joined using nested loop join algorithm. At any instance main memory can hold exactly one block of R and one block of S. What are the total number of block access required to join R and S _____?
