In this week, we will again use our virtual machine. This time, we will be creating two users and granting selected permissions from one user to the other.

First, create a new user with “useradd -m ”. Then, repeat the command for a second user. Set a password for each user with “passwd ”.

Next, we will create a group for our users with “groupadd ”. Add your users to the group with “usermod -G ”.

Test out logging in as your first user with the command “su – ”. Next, we will create three files using the following commands:

• echo “first file” > file1
• echo “second file” > file2
• echo “third file” > file3

You can validate the contents of file1 with “cat file1”. Let’s validate the file permissions of our files with “ls -l”. Take a screenshot of the output. Every file has nine permissions, ignoring the first one. The first three are for the user, the next three are for the group, and the final three are for others.

Next, we are going to adjust permissions so that:

• File1 is only readable and writeable to user1
• File2 is readable and writeable to user1 and members of the group to which you added both users 
• File3 is readable by all users, but writeable only by user1

To make these changes, you’ll use the “chmod” command to adjust permissions, and you’ll need to add file2 to the group our users are in using “chown : file2”. To use the chmod command, there are two syntaxes: octal syntax and letter syntax. We are going to use the letter syntax in these examples. If you know octal syntax, feel free to use that instead.

The format is going to be “chmod ”. The value will be one of u for user, g for group, o for others, or a for all. The will be + to add permissions and – to remove permissions. The will be any of r for read, w for write, or x for execute. Set the permissions of the files to the bulleted list above. Validate your permissions with “ls -l” and take a screenshot of the output.

Then, switch to the second user account and verify the permissions using the following commands.

• cat file1
• cat file2
• cat file3
• echo “first file” > file1
• echo “second file” > file2
• echo “third file” > file3

Take a screenshot of the results of these commands. If the results don’t match expectations, you can switch back to your user1 and adjust permissions again to get it right.

In your submission, include:

• Screenshot of “ls -l” output before changing permissions
• Screenshot of “ls -l” output after changing permissions
• Screenshot of the validation commands as user2

Parameters

• The assignment should be double-spaced, 12-point Times New Roman font, with one-inch margins
• Use APA for citing references and quotations
• See the assignment rubric below for more details

International Foodies is an importer of exotic foods from all over the world. You landed a summer internship with the company and discovered that their product lists and the suppliers they buy from are stored in Excel workbooks. You offer to help by using your newly gained knowledge of Access to create a relational database for them. You will begin by importing the workbooks from Excel into a new Access database. Your manager mentions that she would also like a table that specifies food categories so that you can relate the products you sell to specific categories in the database. You will create a table from scratch to track categories, create relationships between the tables, and create some baseline queries.

Start Access. Open the downloaded   Access file named Exp19_Access_Ch2_Cap_Foodies. Grader has automatically added   your last name to the beginning of the filename. Save the file to the   location where you are storing your files.

You   will examine the data in the downloaded Excel worksheets to determine which   fields will become the primary keys in each table and which fields will   become the foreign keys so that you can join them in the database.
 

  Open the Suppliers.xlsx Excel   workbook, examine the data, and close the workbook. Open the Products.xlsx Excel workbook, examine   the data, and close the workbook.
 

  You will import two Excel workbooks that contain supplier and product   information into the database.
 

  Click the External Data tab, click   New Data Source, point to From File in the Import & Link   group, and then select Excel.   Navigate to and select the Suppliers.xlsx   workbook to be imported as a new table in the current database. Select First Row Contains Column Headings.   Set the SupplierID field Indexed option to Yes (No Duplicates). Select SupplierID   as the primary key when prompted and accept the table name Suppliers. Do not save the import   steps.

Import   the Products.xlsx workbook, set the   ProductID Indexed option to Yes (No   Duplicates), and select ProductID   as the primary key. Accept the table name Products.

Change   the Field Size of the QuantityPerUnit field to 25   in Design view of the Products table. Set the Field Size of ProductID and   CategoryID to Long Integer. Save   the changes and open the table in Datasheet view. Open the Suppliers table in   Datasheet view to examine the data. Close the tables.

You   will create a new table that will enable International Foodies to associate   each product with a food category in the database.
 

  Create a new table in Design view. Add the following fields in Design view   and set the properties as specified:
 

  Add the primary key field as CategoryID   with the Number Data Type and Number assigned to a new category.   (type the period) as the Description. Set the Caption property to Category ID.
 

  Save the table as Categories.

   Add CategoryName with the Short Text Data Type and Name of food   category.   (type the period) as the Description. Change the field size to 15. Set the Caption property to Category Name and the Required property to Yes.

Add   CategoryDescription with the Long Text Data Type. Set the Caption property to Category Description. Switch to Datasheet view and save the   table when prompted. You will enter Category data into the table in the next step.

   You will add 8 records to the Categories table so that you have some sample   data to test in the database.
 

  Add the following records to the Categories table:

Category   ID Category Name   Category Description 

1 BEVERAGES  SOFT DRINKS, COFFEES, TEAS 

2 CONDIMENTS  SAUCES, RELISHES, SEASONINGS

3 CONFECTIONS  DESSERTS,   CANDIES, SWEET BREADS

4 DAIRY   PRODUCTS  CHEESES

5 GRAINS/CEREALS  BREADS, PASTA, CEREAL

6  MEAT/POULTRY  PREPARED   MEATS

7 PRODUCE  DRIED FRUIT, BEAN CURD

8 SEAFOOD  SEAWEED AND FISH

  Close the table.

You will create   the relationships between the tables using the Relationships window.
 

  Add all three tables to the Relationships window. Identify the primary key   fields in the Categories table and the Suppliers table and join them with   their foreign key counterparts in the related Products table. Select the Enforce Referential Integrity and Cascade Update Related Fields check boxes.   Save and close the Relationships window.

You   will use the Simple Query Wizard to create a query of all products that you   import in the seafood category.
 

  Add the ProductName, SupplierID, and CategoryID fields from Products (in that order). Save the query   as Seafood Products.

Add   a criterion in Design view, to include only products with 8 as the CategoryID.

Sort   the query results in ascending order by ProductName. Run, save, and close the   query.

You   want to create a query that displays actual category names rather than the   CategoryIDs. You are interested to know which meat and poultry products are   imported. You will copy the Seafood Products query and modify it to delete a   field, then add an additional table and field.
 

  Copy the Seafood Products query   and paste it using Seafood Or Meat/Poultry   as the query name.

Open   the Seafood Or Meat/Poultry query   in Design view and delete the CategoryID   column.

Add   the Categories table to the top   pane of the query design window. Add the CategoryName   field to the last column of the design grid and set the criterion as “Seafood” Or “Meat/Poultry”.   Run, save, and close the query.

You   will create a query that identifies suppliers and their associated products.   Because there is a relationship between the two tables, you can now pull data   from each of them together as usable information.
 

  Create a query in Design view that includes the Suppliers and Products   tables. The query should list the company name, contact name, phone (in that   order), then the product name and the product cost (in that order).

Sort   the query by company name in ascending order, then by product cost in   descending order. Run, close, and save the query as Company by Product List.

You   determine that the data in the Company by Product List query could be   summarized with a Total row. You will group the records by company name, and   then count the number of products you buy from each of them.
 

  Copy the Company by Product List query   and paste it using Summary of Company by   Product   as the query name.

Open   the Summary of Company by Product   query in Design view and delete the ContactName, Phone, and ProductCost columns.

Click   Totals in the Show/Hide group on   the Query Tools Design tab. Click in the Total   row of the ProductName field, click the arrow, and then select Count.   The records will be grouped by the company’s name and the products for each   company will be summarized.

Modify   the field name of the ProductName column as Product Count:   ProductName to make the field name more   identifiable. Click Run in the   Results group (20 records display in the Datasheet). The results display the   product count for each company that supplies your organization. Save and   close the query.

You want to create a pie chart to show the   percentage each category contributes to the monthly movie downloads.
 

  Select the ranges A5:A10 and F5:F10. Create a pie chart and move it to a   chart sheet named April Pie Chart.

6

3

The   chart needs a descriptive title that is easy to read.
 

  Type April   2021 Downloads by Genre as the chart title, apply bold, 18 pt font size, and Black, Text   1 font color.

5

4

Percentage and category data labels will provide   identification information for the pie chart.
 

  Add category and percentage data labels in the Inside End position. Remove   value data labels and the legend. Apply 14 pt font size and Black, Text 1   font color.

5

You   want to focus on the comedy movies by exploding it and changing its fill   color.
 

  Explode the Comedy slice by 7% and apply Dark Red fill color.

4

6

A best practice is to include Alt Text for   accessibility compliance.
 

  Add Alt Text: The pie chart shows percentage of downloads by genre   for April 2021.   (including the period)

2

7

Next   you want to create a combo chart to depict the monthly totals and percentages   by category.
 

  Display the Data sheet, select the ranges A4:A10 and F4:G10, and then create   a Clustered Column – Line on Secondary Axis combo chart.

4

8

You want to position the chart below the data   source.
 

  Cut the chart and paste it in cell A13. Change the height to 3.5″ and the width to 6″.

5

9

Change   the combo chart title to April 2021 Downloads. Apply Black, Text 1 font color to the chart   title.

3

10

Axis titles will help distinguish the number and   percentage of downloads.
 

  Add a primary value axis title and type Number of Downloads. Add a secondary value axis   title and type Percentage of Monthly Downloads. Apply Black, Text 1 font color   to both value axis titles.

6

11

Now   that you added an axis title for each vertical axis, you can remove the   legend and format the secondary value axis to display whole percentages.
 

  Remove the legend for the combo chart. Display 0 decimal places for the   secondary value axis.

1

12

You want to add some color to the plot area for the   combo chart.
 

  Apply Light Gradient – Accent 1 gradient fill color for the plot area.

5

13

A best   practice is to include Alt Text for accessibility compliance.
 

  Add Alt Text: The combo chart shows the number and percentage of   downloads by genre for April 2021. (including the period).

2

14

To provide a visual summary of the weekly totals   for each genre, you will insert sparklines.
 

  Select the range B5:E11. Insert Line Sparklines in the range H5:H11. Apply   Black, Sparkline Style Dark #4

10

15

Displaying   the markers helps identify the specific points on the sparklines. You will   also change the high point to a different color to stand out.
 

  Show the high point and markers for the sparklines. Change the high point   marker color to Red.

5

16

Your last major task is to create a bar chart for   weekly downloads.
 

  Select the range A4:E10. Create a stacked bar chart. Move the chart to new   chart sheet. Type Weekly Downloads for the sheet name. Apply Style 8 chart style.

14

17

Add a   chart title above the bar chart and type April 2021 Weekly Downloads by Genre.

18

Increasing the font size will make the chart   elements easier to read.
 

  Apply 11 pt font size to the category axis, value axis, and the legend for   the bar chart.

6

19

Because   the largest value is less than 9,000, you can reduce the maximum bound in the   chart. In addition, you want to display the category labels in the same order   that they are in the worksheet.
 

  Change the maximum bounds for the value axis to 9000 and set the Major Units to 500 for the bar chart. Use the Axis   Options to format the category axis so that the category labels are in   reverse order in the bar chart.

5
