Question 1:

1. What were the benefits of implementing an EDW at Isle? Can you think of other potential benefits that were not listed in the case?

2. What are ROLAP, MOLAP, and HOLAP? How do they differ from OLAP?

Question 2:

FORENSIC DESIGN ASSESSMENTS

This task relates to a sequence of assessments that will be repeated across Chapters 6, 7, 8, 9 and 10. Select any example of a visualisation or infographic, maybe your own work or that of others. The task is to undertake a deep, detailed ‘forensic' like assessment of the design choices made across each of the five layers of the chosen visualisation's anatomy. In each case your assessment is only concerned with one design layer at a time.

For this task, take a close look at the annotation choices:

1. Start by identifying all the annotation features deployed, listing them under the headers of either project or chart annotation

2. How suitable are the choices and deployment of these annotation features? If they are not, what do you think they should have been?

3. Go through the set of ‘Influencing factors' from the latter section of the book's chapter to help shape your assessment and to possibly inform how you might tackle this design layer differently

4. Also, considering the range of potential annotation features, what would you do differently or additionally?

Question 3:

Data visualization has been around for some time. We remember in the late 90's being struck by the pure awesomeness of "XPLANATiONS" infographics published in Business 2.0 magazine. Not long after, we discovered from the great Edward Tufte, the rich history of data visualizations going back perhaps to the earliest of times.

What are effective ways to leverage interactivity in data visualizations? Provide 3 examples of how you would effectively use interactivity in data visualization.
