Expert Solution & Answer
Chapter 8, Problem 8.8RQ
Explanation of Solution
Transformation of data:
- The data that are present in data warehouse contains a summary of different data.
- The data that are present in warehouse needs to be used correctly so that the data need to be aggregated.
- The data contents that are present need to be consolidated such that the data can be used by the operations team in an effective way.
- Hence, the data contents get stored in one format and will be used in another format after performing consolidation operations...

- What other data science tool are available besides the ones mentioned in class?arrow_forwardA wide variety of everyday objects (including attractions at amusement parks, autos, elevators, and ovens) are really computers or information systems these days. The typical person would not connect them to a computer or database. The benefits are obvious, but are there any downsides to consider? As an example, if you rode a computer-controlled roller coaster, how confident would you be in its safety? As more and more mundane tasks are automated by computers, we have to ask whether the benefits are worth the cons. If so, then explain why.arrow_forwardWhat's the short answer to the question: "Data vs. information?"arrow_forward
