Question 15

Dashboards are a style of reporting that depicts KPIs,operational or strategic information with intuitive and interactive displays.

Accepted Answer

Dashboards are a style of reporting that use visualizations to provide quick and easy access to important data and KPIs. They are interactive, allowing users to explore the data in different ways, and intuitive, making it easy to understand and analyze the information being presented. Overall, dashboards are an effective way to monitor performance and make data-driven decisions.

Question 16

According to Gartner's research,in 2014 the data analytics market split into two segments: the traditional BI market and the new data discovery market.

Accepted Answer

Gartner's research in 2014 identified the traditional BI market and the new data discovery market as two distinct segments of the data analytics market.

Question 17

A disadvantage of dashboards is that users need to log into multiple applications to see how the business is performing.

Accepted Answer

Dashboards consolidate data from various sources into one place, so users don't need to log into multiple applications.

Question 18
