Read the brief case below. Using Tableau Desktop Profession Edition, complete the questions.

Downtown Office Supply

Downtown Office supply is a small family owned store in a small suburb. In order to maintain and grow the business the owners want to do some analysis to see how their sales are doing. Management wants to see how the company did last year and make some decisions about what products to keep along with staffing for busy times of the year.

Instructions and Submission Requirements: Use the Excel workbook provided and import the data to Tableau. Complete the tasks below. Note that some tasks ask additional questions and observations (eg task 1 asks about outliers). Include your brief responses to each page as part of task number 6 and in summary. Upon completion you will submit your Tableau file (.twbx) to eLearning. (Only one submission is required)

1. Open Tableau.

2. Import the Excel file – Final_Orders_Clean.xlsx.

3. Create an innerjoin between market_fact table and the rest of the tables as shown below[ Hint: Drag and Drop the tables in the Data Source space]

Note that the version 2020.4 will give the following “relationship” diagram. You can use this (but it does not show “joins”) :

But if you want to change the view and see “joins” (diagram below), do the following:

1. Drag “market_fact” to canvas.

2. “Double click” on “market_fact”.

3. This will chane the icon to the one below (with a blue border on left). After this, you can drag and drop other tables as shown below.

4. Double check your join statements to make sure the correct primary key and foreign keys are in place. [HINT: order_id and ord_id]

5. Click on “Goto Worksheet” at the bottom to insert a blank worksheet for your questions For each question, take a screen shot of your visualization. Be sure to save your Tableau file and upload the Tableau file (twbx).

Exercise Tasks: Follow the directions for each task below and submit your Tableau file (.twbx) to eLearning to receive credit for the assignment. Note that your responses to each task will be added as notes, as described in task 6 below.
