This definition emphasizes that Big Data is characterized not just by its size but by the challenges it presents to traditional database tools.
Q2.
What is the main source of value derived from Big Data, according to MGI?

a.

The size of the dataset.

b.

Creating transparencies.

c.

Discovering needs and exposing variability.

d.

Human decision-making.

Discuss
Answer: (c).Discovering needs and exposing variability. Explanation:The main source of value derived from Big Data, as explained by MGI, includes creating transparencies (making data more visible), discovering needs and exposing variability (identifying patterns and variations in data), segmenting customers (dividing customers into groups for targeted strategies), and replacing/supporting human decision-making with automated algorithms (using data-driven insights for decision-making and innovation).
Q3.
What is the concept of "Big Data Search" as described by David Gorbet?

a.

Searching for large volumes of data.

b.

Combining data explorations with analytics.

c.

Using a single formula for extracting value from Big Data.

d.

Hiding insights from data explorations.

Discuss
Answer: (b).Combining data explorations with analytics. Explanation:The concept of "Big Data Search" as described by David Gorbet implies that there is no single formula for extracting value from Big Data; it depends on the application. It involves the ability to search through large volumes of complex data from multiple sources via interactive queries, which can provide organizations with new insights about their products, customers, and services.
