DigitalArts is a video gaming service that offers subscription-based access to online video games. You need to analyze sales performance. a. Create a star schema model for the data that will allow you to compare revenue subscription counts by age groups. Indicate which tables are the fact, the what, and the occurs tables. Show the table relationship and their cardinalities. Provide at least three examples of columns for each table. Provide a example of a calculated column and an example of a measure. b. Define the algorithm for the calculated column in your example. What information modeling pattern is used for this column? c. Define the algorithm for the measure in your example. What information modeling pattern is used for this measure? Upload an Excel or zip file that contains your algorithm and a star schema. (Zip is required if you choose to use Power BI or Tableau.) Provide clear comments regarding the software used and the location within the Excel, PowerBI or Tableau file where your visualization is presented.

Given the assumptions above and the page table below, translate the following virtual addresses (expressed as base ten integers) to physical addresses (also base ten integers). If the corresponding page is not resident in memory (NR), indicate a page fault. 2. Hint: rather than translating these values to binary or hexadecimal, you can use the following formulas: = virtualAddress/pageSize] where x is x rounded down to the рageNum nearest integer offset dividing x by y. = virtualAddress mod pageSize where x mod y is the remainder after physicalAddress frameNum x pageSize offset.
