Hint for Assignment #4 (ETL and Pivot Tables)

I got quite some questions related to Part 4, Question (b) of Assignment #4, which asks you to create a pivot table first, and then use the excel AVERAGE function in a separate cell outside the pivot table.

Here is an example of what I mean by “use the Excel AVERAGE function to average those values … in a separate cell outside the Pivot Table.”

Let me know if you have any questions.

If so, download the latest Mac version of Microsoft Office for free by following the instructions here: https://computerservices.temple.edu/office-365. It is free for Temple students.

More on Assignment 3 (SQL Part 2)

1. To start Assignment 3, you need to complete ICA #6 first. Want to check if you did ICA #6 correctly? Take a look at the solution key that I posted under Course Materials. If you had any mistake in your solution, follow these steps:

  1. In MySQL Workbench, delete your Company table;
  2. Copy and paste the statements from the file “ICA #6 SQL statements” to your MySQL Workbench;
  3. Replace the schema names “mxxws” with your schema name (mxx should be your MySQL username);
  4. Run all the statements. Make sure you did not get any error message;
  5. If everything works, you can start Assignment 3 now.

2. BOOLEAN data type. In the Contact table, the field IsMain has a BOOLEAN data type. If you do not know how to handle BOOLEAN data type, here is short tutorial that might help: More on MySQL BOOLEAN Data Type
