Consider two relations R and S of size 1200bytes and 1000 bytes respectively. The size of atuple in both relations is 20 bytes. The block sizeof the system is 100 Bytes. How many extrablock transfers would be required, in the worstcase, if nested loop join is used instead of blocknested loop join technique to compute thenatural join?

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

Question

Consider two relations R and S of size 1200
bytes and 1000 bytes respectively. The size of a
tuple in both relations is 20 bytes. The block size
of the system is 100 Bytes. How many extra
block transfers would be required, in the worst
case, if nested loop join is used instead of block
nested loop join technique to compute the
natural join?
