Assignment Details

You are trying to decide the best methodology to approach developing your online product ordering system. You have heard that using object-oriented programming will save you time and allow you to reuse many of the functions that you develop for this application. You also recognize that there will be requests for future functionality to be added to this ordering application after you launch the first version.

You have decided to evaluate the similarities and differences between structured procedural programming and object-oriented programming (OOP). You also are looking at how the object-oriented concepts can enhance your overall design and development of this application.

Using the online library, the Internet, and all resources, research at least 2 sources to support your response.

Within the Discussion Board area, write 3 paragraphs that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas:

Given an abstract class A, and an Interface I as shown in the diagram (“Inheritance”), respond to the following questions:

  • What are the details of inheritance for the Class B that Extends Abstract Class A? 
  • What are the details of inheritance of the Class J that Implements interface I?
  • How would these types of inheritance be used in a program to solve a real-world problem? 
  • What advantages do these types of inheritance provide?

Interpreting HTML Markup

Unit 4 DB: Interpreting HTML Markup

Unit 4 DB: Interpreting HTML MarkupComplete the Chapter 6 reading, up to and including Exercise 6.2 (Creating “Hello, world!” in HTML). Then go to page 249, and complete the Chapter 6 Lab, where you view the markup behind two websites. After exploring the answers to the seven questions for both websites, and recognizing the components of HTML markup, in your discussion post explain your experience. Could you easily identify the page contents compared to the page code? What languages did the pages use, and were they easy to identify? Why do you think the website developers used those languages?

Chapter 6 Lab

If you want to become a programmer, you will need to study one or more languages. You have a variety of options available, including online materials, in-person classes, and study guides. While this chapter certainly didn’t teach you everything you need to know to become a programmer, you did learn some concepts and a bit about how to read and understand code. For this lab, you will look at a few different websites and see how their code was constructed.

Open the website www.youtube.com in Chrome or Edge. To view the source code in Chrome, right-click the page, and choose View Page Source. In Edge, press the F12 key to show the code. (Or, you can click the Settings And More menu—the three horizontal dots in the upper-right corner—and click F12 Developer Tools.)

Here are some questions for you:

  1. In what language is the page written?

JavaScript  

  1. What organizational techniques do you see?
  2. Do you see any branching or looping logic?
  3. Does the page use functions at all?
  4. Which scripting languages are used on the home page?
  5. Find a string of text. Can you find where that string is on the web page?
  6. Can you find any instances of where a background color is set?

Excel Chapter 3 Capstone – Gym 

  

Project Description:

You and a business partner opened a fitness gym three years ago. Your partner oversees managing the operations of the gym, ensuring the right equipment is on hand, maintenance is conducted, and the appropriate classes are being offered with the right trainers and staff. You oversee managing the business aspects, such as marketing, finance, and general personnel issues. The business is nearing the end of its third year. You have put together the financials, and now you want to show the data more visually because you know it will make more sense to your business partner that way. You want to create charts and insert sparklines that show the trends to discuss with your partner.

     

Start Excel. Download   and open the file named Exp19_Excel_Ch03_Cap_Gym.xlsx.   Grader has automatically added your last name to the beginning of the   filename.

 

 

You will create a pie   chart to focus on the expenses for the current year.
 

  Insert a 2-D pie chart using the ranges A11:A19 and D11:D19 on the Income   worksheet.

 

 

Move the chart to a   new chart sheet named Expenses. Move it to the right of the   Membership sheet.

 

The chart needs a   descriptive, easy-to-read title.
 

  Change the chart title to Expenses for Year 3 and change the font   size to 20.

 

You want to create a   clustered bar chart.
 

  Insert a clustered bar chart using the ranges A4:D4 and A11:D19 on the Income   worksheet. 

 

You want to place   this chart and other charts on a Summary worksheet to look at trends.
 

  Move the chart as an object on the Summary worksheet. Cut the bar chart and   paste it in cell I1.

 

The chart should have   a descriptive title to explain which expenses are excluded.
 

  Change the bar chart title to Expenses (Without Payroll and Cost of Sales).

 

You want to filter   out the Payroll and Cost of Sales to focus on other expenses. The bar chart   displays expenses the first expense (Advertising) at the bottom of the   category axis. You want to reverse the categories to display in the same   sequence as the expenses are listed in the worksheet.
 

  Apply a chart filter to remove Payroll and Cost of Sales. Select the category   axis and use the Format Axis task pane to display categories in reverse   order. Change the Maximum Bound to 25000.
 

  Mac Users: Apply the filter using Select Data and Switch Row/Column. Be sure   to switch the rows and columns back after filtering the data.

 

You decide to format   the pie chart with data labels and remove the legend because there are too   many categories for the legend to be effective.
 

  Display the Expenses sheet and remove the legend. Add Percent and Category   Name data labels and choose Outside End position for the labels. Change the   data labels font size to 10.

 

You want to emphasize   the Education & Training slice by exploding it.
 

  Explode the Education & Training slice by 12%.

 

 

Add the Light   Gradient – Accent 2 fill color to the chart area.

 

You create another   chart showing the Balance sheet items. You change the chart to a clustered   column and switch the row and column data to focus on each balance sheet   item.
 

  Insert a stacked column chart using the ranges A4:D4, A10:D10, A15:D15, and   A16:D16 on the Balance sheet.
  Change the chart type to Clustered Column and switch the rows and columns in   the chart.

 

You want to move the   column chart to be on the Summary worksheet along with the bar chart.
 

  Move the column chart to the Summary worksheet. Cut the chart and paste it in   cell A1.

 

The column chart   needs to have a descriptive title to indicate the data comes from the Balance   
  sheet.
 

  Change the title to 3-Year Balance Sheet.

 

The last chart will   be a line chart to show the trends in Memberships.
 

  Insert a line chart using the range I3:L15 on the Membership worksheet. 

 

You want to move the   line chart to be on the same Summary sheet as column and bar charts.
 

  Move the line chart to the Summary worksheet. Cut the chart and paste it in   cell A17.

 

Because the lowest   value is between 200 and 300, you will change the vertical axis at 200   instead of 0.
 

  Adjust the vertical axis so the Minimum Bound is 200 and display a   vertical axis title # of Memberships for the line chart.

 

Apply Chart Style 4   and change colors to Monochromatic Palette 8 for the line chart.

 

Move the legend to   the top of the chart and add the chart title 3-Year Membership Trends.

 

It is a best practice   to add Alt Text for each chart for accessibility compliance.
 

  Display the pie chart and add Alt Text: The pie chart displays   percentage of expenses for Year 3. (including the   period)

 

Display the column   chart and add Alt Text: The column chart displays total assets,   total liabilities, and retained earnings for three years. (including the period)

 

Display the bar chart   and add Alt Text: The bar chart displays expenses for three   years without payroll or cost of sales. (including   the period)

 

Display the line   chart and add Alt Text: The   line chart displays monthly trends in memberships for three years. (including the period)

 

You want to add   sparklines to the Daily Attendance Trends. You add high points to emphasize   which time of day is the most popular for your membership.
 

  Select range B16:F16 on the Membership worksheet. Insert Column Sparklines using   data from the range B6:F14. Display the high points for the sparklines.

 

Insert a footer with Exploring   Series   on the left, the sheet name code in the center, and the file name code on the   right on the Membership, Expenses, and Summary sheets individually. Change to   Normal view.

 

Save and close Exp19_Excel_Ch03_Cap_Gym.xlsx. Exit   Excel. Submit the file as directed.
