Discuss
Answer: (b).Because energy consumption is a new problem introduced by Big Data Explanation:Energy consumption is considered a critical side effect of dealing with Big Data.
Q12.
Why does the query-processing paradigm need to change with more data?

a.

To ensure processing of all available data

b.

To reduce energy consumption

c.

Because past solutions are still effective

d.

Because processing all data is not possible or necessary

Discuss
Answer: (d).Because processing all data is not possible or necessary Explanation:With more data, the query-processing paradigm needs to change because processing all data is not possible or necessary.
Q13.
In the context of business analytics, why is changing the processing paradigm considered important?

a.

To ensure efficient utilization of resources

b.

To allow for more scalability with Big Data clusters

c.

To reduce the need for data indexing

d.

To provide fast answers and avoid wasting time

Discuss
Answer: (d).To provide fast answers and avoid wasting time Explanation:Changing the processing paradigm in business analytics is important because it allows for fast answers and avoids wasting time, especially in situations where answers are needed quickly.
Q14.
What is the primary purpose of data exploration in the context of query processing for Big Data?

a.

To guarantee complete and correct answers to user queries

b.

To facilitate instant data analysis without user interaction

c.

To assist users in discovering interesting patterns when the exact query is unknown

d.

To enforce strict contracts for database usage

Discuss
Answer: (c).To assist users in discovering interesting patterns when the exact query is unknown Explanation:Data exploration in the context of query processing for Big Data is primarily about assisting users in discovering interesting patterns when the exact query is unknown.
Q15.
What is a common characteristic of scenarios where data exploration is needed?

a.

Discuss
Answer: (a).A daily stream of Big Data Explanation:Scenarios requiring data exploration often involve a daily stream of Big Data, typically in the order of multiple terabytes.
Q16.
How should next-generation database systems interpret queries?

a.

As contracts that cannot be modified

b.

By their intent, rather than as rigid contracts

c.

With a focus on instant data processing

d.

With a primary goal of guaranteeing complete answers

Discuss
Answer: (b).By their intent, rather than as rigid contracts Explanation:Next-generation database systems should interpret queries by their intent, rather than as rigid contracts.
Q17.
What is the key benefit of systems that support data exploration?

a.

Ensuring complete and correct answers to all queries

b.

Minimizing the need for incremental data updates

c.

Guiding users toward a predefined path for data analysis
