Expert Solution & Answer
Chapter 22, Problem 3PE
Explanation of Solution
When two or more operations run in a concurrent manner on different processors in such a way that one of the operation consumes records in parallel with other operation will actually also produce them is called as pipelined parallelism.
a)
Reason:
Even though many processors are available, it is recommended to execute many operations in a pipeline on a singl...
Explanation of Solution
b)
Justification:
- When the machines contain shared memory architecture then the transfer of records betw...
Explanation of Solution
c)
Justification:
- When the pipelined parallelism is independent then two operations that take place are also considered to be independent but there is chance where both operations can provide their output to the third operator...

(Short-answer) b. Continue from the previous question. Suppose part of the data you extracted from the data warehouse is the following. Identify the missing values you think exist in the dataset. Use Column letter and Row number to refer to each missing value in the dataset. Please write down how you want to address each particular missing value (you can group them if they receive same treatment). For imputation, you do not need to calculate the exact imputed values but just describe what kind of value you want to use to impute.

For coding simplicity, follow each output integer by a space, including the last one. Then, output a newline.
