Answer 1

Expert Solution & Answer

Chapter 22, Problem 14E

Explanation of Solution

a)

In a shared parallel architecture, neither the memory nor the disk is shared between processors.

Consider a workload which consists of large number of small transactions and utilizes shared nothing parallelism.

Intra –query parallelism is implemented while executing a single query in parallel on multiple processors and disks...

Explanation of Solution

b)

When workload gets distributed amongst processors, some of processors might get a larger number of tuples than others and it is called a skew...

Explanation of Solution

c)

Consider the given case with two tables, account and account type master record.

Since most of the transactions access account records, so using intra-query parallelism to follow the below steps.

Divide the data into equal numbers for the disks with each processor.

Assign a home processor Pi to each page of data which is on disk Di
