Exercise 2

<p><strong>Chapter 8/Exercise 2</strong></p><p>This exercise demonstrates how to implement a CASE Switch to process data differently depending on the day of the week. This is a very common task in data warehousing.</p><p>In this example, we want to process the data as follows:</p><ul><li><p>Every <strong>Wednesday</strong>, create a <em>Box Plot</em> image of the scaled price.</p></li><li><p>No processing during <strong>the weekend</strong>.</p></li><li><p>On any other day, just filter out some columns.</p></li></ul>
