Please see attachment before proceeding with directions below.

                                                           

Case Assignment

Entity-Relationship Modeling 

  1. Fill in the column headings in row one of each table (Customer,  Employee, and Sales Order) with the data items (attributes) you believe  belong in the table.
  2. Draw an ER diagram for the three tables: Customer, Employee, and Sales Order.
    Suppose  the Sales Order Table also contains information for an employee who  makes a sale. If you have an ERD drawing tool such as Visio, you could  draw the diagram using the tool and copy it into your document. You  could also draw it on paper, scan it, and insert it into your document.  If you can’t do either of the above, you could write down the table  schemata and describe the relationships among them.
  3. Submit the document. Make certain the table title, course number, and module and Case ID are on the work you submit.
  4. Describe the major points you learned in the readings especially on  entity relationship modeling and what lessons you have learned in this  exercise. (at least half a page).

Please note that you will need to study the background materials for your assignment.

Project Description:

You are considering several cities for a vacation. In particular, you are interested in Washington DC, Philadelphia, and Boston. You will format a list of memorials in DC, add Sparklines to compare the number of visitors over a 15-year period, and create a bar chart to illustrate annual visitors at each memorial. In addition, you will create a table of sightseeing locations, sort and filter the data, apply conditional formatting, and add a total row to display average time needed to spend at each memorial. Finally, you will complete a worksheet by adding formulas to compare estimated major expenses for each city.

     

Start   Excel. Download and open the file named Exp19_Excel_AppCapstone_IntroAssessment_   Travel.xlsx.   Grader has automatically added your last name to the beginning of the   filename.

 

On the DC sheet, check the   spelling and correct all misspelled words.

 

On the DC worksheet, select the   range A4:G4, wrap the text, apply Center alignment, and apply Blue, Accent 5,   Lighter 60% fill color.

 

On the DC worksheet, merge and   center the title in the range A1:G1. Apply Blue, Accent5 cell style and bold   to the title.

 

 

On the DC worksheet, change the   width of column A to 34.

 

 

On the DC worksheet, select the   range C5:F10 and insert Line Sparklines in the range G5:G10.

 

 

On the DC worksheet, select the   range G5:G10, display the high point sparkline marker, and change the color   of the high point markers to Dark Red.

 

 

On the DC worksheet, select the   range G5:G10, apply Same for All Sparklines for both the vertical axis   minimum and maximum values.

 

 

On the DC worksheet, select the   ranges A4:A10 and C4:F10 and create a clustered bar chart. Apply the   Monochromatic Palette 12 chart color. Apply the gradient fill to the chart   area. Do not change the default gradient options.

 

Cut the chart and paste it in   cell A13. Change the chart height to 6″ and the chart width to 7″.   Add Alt Text The bar chart shows the number of visitors to each   memorial for the years 2002, 2007, 2012, and 2017.

 

 

Change the chart title to Annual   Visitors. Apply   Blue, Accent 5, Darker 25% font color to the chart title and category axis   labels. Change the value axis display units to Millions. Add Primary Minor   Vertical gridlines to the chart.

 

 

Apply data labels to the outside   end of the 2017 data series. Apply Number format with 1 decimal place to the data   labels.

 

 

On the Places sheet, find all   occurrences of BOS and replace them with Boston.

 

On the Places sheet tab, convert   the data to a table, assign the table name Tourist_Attractions, and apply Blue, Table Style   Medium 2.

 

On the Places sheet, freeze the   top row.

 

On the Places worksheet, sort   the data by City in alphabetical order and then within City, sort by   Sightseeing Locations in alphabetical order.

 

On the Places worksheet, add a   total row to display the average of the Time Needed column. Apply Number format   with zero decimal places to the total.

 

On the Places worksheet, select   the values in the Time Needed column and apply conditional formatting to   highlight cells containing values greater than 60 with Light Red Fill.

 

On the Places worksheet, apply a   filter to display only fees that are less than or equal to $10.

 

On the Cities worksheet, click   cell F4 and enter a formula that will subtract the Departure Date (B1) from   the Return Date (B2) and then multiply the result by the Rental Car per Day   value (F3).

 

 

On the Cities worksheet, click   cell E13. Depending on the city, you will either take a shuttle to/from the   airport or rent a car. Insert an IF function that compares to see if Yes or   No is located in the Rental Car? Column for a city. If the city contains No,   display the value in cell F2. If the city contains Yes, display the value in   the Rental Car Total (F4). Copy the function from cell E13 and use the Paste   Formulas option to copy the function to the range E14:E18 without removing   the border in cell E18.

 

 

On the Cities worksheet, click   cell F13. The lodging is based on a multiplier by City Type. Some cities are   more expensive than others. Insert a VLOOKUP function that looks up the City   Type (B13), compares it to the City/COL range (A7:B10), and returns the COL   percentage. Then multiply the result of the lookup function by the Total Base   Lodging (B5) to get the estimated lodging for the first city. Copy the   function from cell F13 and use the Paste Formulas option to copy the function   to the range F14:F18 without removing the border in cell F18.

 

 

On the Cities worksheet, click   cell H13 and enter the function that calculates the total costs for the first   city, including airfare, shuttle or rental, lodging, and meals. Copy the   function in cell H13 and use the Paste Formulas option to copy the function   to the range H14:H18 without removing the border in cell H18.

 

 

On the Cities worksheet, select   the range E14:H18 and apply Comma Style with zero decimal places. Select the   range E13:H13 and apply Accounting Number format with zero decimal places.

 

 

On the Cities worksheet, in cell   I2, enter a function that will calculate the average total cost per city. In   cell I3, enter a function that will identify the lowest total cost. In cell   I4 enter a function that will return the highest total cost.

 

 

Group the three worksheets and   create a footer with Exploring Series on the left side, the sheet tab code in the   center, and the file name code on the right side.

 

On the Cities worksheet, select   Landscape orientation, set a 1″ top margin, and center the worksheet   data horizontally on the page.

Wk 5 – Apply: Signature Assignment: Measuring Progress and Requirements

 

Assignment Content

  1.  Measuring progress and requirements in a project can be completed through performance testing. As you review the results, it leads to ways to maintain the project progress. In this week’s assignment you will develop requirements that need measurable results through performance testing. Review the scenario and complete the activity below.

    The Recreation and Wellness Intranet Project team is working hard to ensure that the new system they develop meets expectations. The team has a detailed scope statement, but the project manager, Tony Prince, wants to make sure they’re not forgetting requirements that might affect how people view the quality of the project. He knows that the project’s sponsor and other senior managers are most concerned with getting people to use the system, improve their health, and reduce healthcare costs. Users want the system to be user-friendly, informative, fun to use, and fast.

    Complete the following in a Microsoft Word document.

    Develop a list of 6 quality standards or requirements related to meeting the stakeholder expectations described in the Running Case.

    Write a 45- to 90-word brief description of each requirement. For example, a requirement might be that 90 percent of employees have logged into the system within 2 weeks after the system rolls out.

    Write a 175-word explanation based on the list of standards and requirements on how you will measure progress on meeting the requirements. For example, you might have employees log into the system as part of the training program and track who attends the training. You could also build a feature into the system to track usage by username, department, and other criteria. Support your answer with 1 credible source outside of the course materials.

    Submit your assignment.
