[SOLVED] example of company performance analysis. select two companies and compare their financial structures including WACC, book value, and market value.

United States steel is a steel production company located in Pittsburgh, Pennsylvania. The company was founded in 1901. The company area of operation includes the USA and central Europe. The company generated revenue of 10 billion in 2016 financial year. Facebook, on the other hand, is a social media platform founded in 2004. The company is based in Menlo Park California. The company generated a revenue of 27 billion 2016 financial year. These companies operate in different industries. Therefore, the underlying conditions that influence the earning of companies may be totally different.  Besides, their assets and expenses are totally different. A company like Facebook invest most on research and development while a company like US steel invest heavily on plant and equipment.

United States steel (X) have 176,000,000 outstanding shares while Facebook have 2,930,000,000 outstanding shares.  The price per share for United States steel (X) is 35.48 USD and for Facebook (FB) is 161.89 USD. Therefore, the value of United States Steel (X) is 6,244,480,000 USD and for Facebook (FB) is 474,337,700,000 USD (Yahoo, 2019).  The book value of the company is calculated by taking the total asset value less total liability.  Therefore the book value of each company is as calculated below

Document format:

§  limited to 8 pages (excluding title page, references, and appendix),

§  Double-spaced, 12 point Times New Roman font, 1” margins, Bottom-right page numbering.

 

Note:   Submitted report must be either in MS Word or PDF format and titled: “Assignment2_LastName”.

Only one document will be allowed to be submitted.

 

Content (note that the document must have clearly marked sections for the items listed below)

 

1)      Title page (1 page limit): course number and term, assignment number and project title, student name and contact information, instructor’s name. Format it so it looks pleasant and presentable. Follow formatting guidelines above.

 

2)      Introduction.  Provide a brief outline of the dataset you are using for this assignment. Briefly describe the content of the data. Include a screenshot of the data (not all, but partial as far as all relevant variables are visible).
 

3)      Data preparation – handling missing data, removing irrelevant variables

8)      Appendix (4 page limit):

a)      Appendix A: Include any appropriate workbooks and/or screenshots (figures, tables, diagrams) used in this assignment. Make sure all tables, figures, or diagrams are properly numbered and titled. For example, “Table 1. Model Results”. Make sure all tables or figures or diagrams are easily readable and visually presentable.

 

General guidance

§  Assignments that: 1) adequately address all required tasks; 2) are submitted on time; 3) are properly formatted (APA format for references, no typos or misspelled words, no grammar errors, cover page, etc.) will receive a grade of B (80-89, depending on content).
 

§  In order to increase (but not guarantee) your chances of receiving a higher grade, you need to show clear evidence of critical thinking. Critical thinking can take many forms, depending on the type of assignment. In some instances, showing greater depth (e.g., such as creating more models, looking at more than one insightful fact or relationships, and comparing them on key criteria) is one method for providing evidence of critical thinking. In other cases, it might include providing more explanation to include the pros and cons of the approach used or the arguments in favor and against the proposal as well as some criteria for choosing among the alternatives. Still another example would be providing significant insights as to how the assignment outcome would benefit (or would meet resistance) in your organization and what steps might be employed to facilitate acceptance. Certainly, this is not a complete list, but gives some examples of critical thinking aspects.

Put your row count in the green box in cell D5.

Professor Victoria Emmerline is set to retire immediately before spring semester.  You want to generate a list of all students who are currently enrolled in any class she is teaching this spring, so you can reach out to them and let them know there will be a different professor.  Assume each class she teaches could be assigned to a different professor – i.e. if Professor Emmerline was set to teach Calculus I and Calculus II, it’s possible Calculus I will be assigned to Professor X and Calculus II will be assigned to Professor Y.

Generate SQL code to make a report which will do the following

·       Generate a concatenated class name/number string, such as “FIN 200” from something in the Finance Department where the course number is 200

·       Print that class name/number string in the first column of your report

·       Print the class description (such as “Introduction to Finance”)

·       List the student’s first name and then last name

·       List the offering term and the format (online or in person)

·       List the professor’s first name and last name

·       Sort your output ascending by the class name/number string, so “FIN 200”, “FIN 120” and “ART 100” would be sorted in the following order:  “ART 100”, “FIN 120”, “FIN 200.”

·       Within the same class, further sort your output so it’s alphabetical by student last name, student first name

Some faculty are grumbling that certain professors have an easy teaching load, defined as only a few courses with low capacity, while others have a heavy load of many courses with high seat counts.  Run a query to help answer this question. 

Your output should contain the faculty ID, faculty name (first and last – it’s fine to have this as two separate fields, also fine to concatenate together), the largest capacity class the faculty member is assigned to teach, the maximum possible total student load (sum of all the course capacities), and the number of classes the faculty member is teaching.

Include all faculty members, even if they are not assigned to teach any courses.  Include courses only if they are taught by a faculty member.  Sort your output ascending by the number of courses taught, with the professors with the fewest courses at the top.

Assignment 3.1 This assignment is worth 70 points

Assignment 3.1

 

This assignment is worth 70 points and the full rubric is on the bottom of the page.

 

It’s time to go to the opera!  You are going to use MySQL Workbench’s EER tool to create an Entity-Relationship diagram for the Civic Center Opera House.  You will then engineer that to produce MySQL script(s) which will create and load the database schema with the information below.  Finally, you will query your database to prove it is working.

 

Here is the relevant information.

·         Susie attended Madame Butterfly and spent $25 on the ticket for the 1/11 performance, and then went to see La Traviata on 10/3 for $100.  She also went to see Carmen for $30 on 10/10.

·         Lee attended Madame Butterfly and spent $25 on the ticket for the 10/21 performance.

·         Jackson attended Carmen and spent $30 on the ticket for the 5/12 performance.  He also went to see La Nozze di Figaro on 1/20, and paid $100 for the ticket.

·         Bobby attended Carmen and spent $30 on the ticket for the 1/26 performance, and then went to see La Boheme on 8/14 for $50.

·         Margaret attended La Nozze di Figaro and spent $100 on the ticket for the 2/22 performance, and then went (with Jackson) to see Carmen on 5/12 for $30.

·         Ulysses attended Rigoletto on 10/21 and spent $35 on the ticket.

·         Each ticket has an option to have a “Backstage Pass” option.  There is no additional cost associated with this, just a marking on the ticket that the backstage pass was selected.

·         Backstage passes were selected by Margaret at all of her operas, and by Jackson when he went with Margaret to Carmen on 5/12.   No other tickets chose a backstage pass.

 

Additional assumptions you should make:

·         Assume all tickets for the same opera cost the same.  For example, all tickets for Madame Butterfly are $25.

·         All operas occurred last year.  For example, if it is 2020 now, and the date says “November 11,” assume it was November 11, 2019.

 

Normalize this database and implement in MySQL Workbench using this information. 

 

Name your database schema “CivicCenter.”  Please try to use this exact name to make it easier to grade.  It is not case-sensitive so it’s OK to use “civiccenter” or CIVICcenter.”  Do not use “Civic_Center” or “civic-center.” 

 

You may use as many or as few tables as you see fit. 

 

 

Your deliverables are:   

1.       “XXX_Civiccenter_ERD.pdf” where XXX are your initials.  This is a pdf of an entity-relationship diagram made using MySQL Workbench’s modeling tool (you can find this under File Menu -> Export.) 

a.       Entity-relationship diagrams made using other tools will not earn full points.

b.       The diagram should show all entities you use (it’s OK to use more than one page if you need to, and you can cobble together screenshots if you need.)

c.       All entities should show all fields and keys; expand the boxes or rearrange them if you need to.

d.       All relationships and cardinalities should be easily visible

e.       All relationships should have text sentence(s) labeling them.  For example, if this were the pet database, you might write, “Each pet must have one and only one owner.  Each owner may have zero or more pets.”

Question 5 (2 points)

 

Question 5 options:

[SQL Week 2 Question 200-505] 

You want to report on a certain group of your products. Select

Only customers who have a balance of 0

Only shipments which were sent by employees whose employee location is California, Maryland, or New York

Only products which have had a shipment

Only employees who have made a shipment

Only customers who have received a shipment

Compute the total quantity of shipments which meet these criteria

Aggregate it by manufacturer and by product name. This means each manufacturer/product name combination appears on only one row in the table. If a manufacturer makes more than one product, it’s OK if it shows up once per product.

Sort it descending by the sum of the shipment quantity, so the largest shipment quantity shows up on top. Within shipment quantities, sort it alphabetically on manufacturer and then product name.

Your results should look something like this:

What is the total shipment quantity for General Widgets' "Widget Maximus" product?  This would be in the green "A"  in the screenshot above.

 

Which company had Total Shipments of 2 for the Twisters?  This would show up in the blue letter "B" above.

[SQL Week 2 Question 200-503]

You suspect certain employees are not servicing very many shipments, and some may not have any shipments at all.

Create SQL to run a report which will

List all your employees and the customers they serviced along with the number of shipment for each customer. Include all employees, including those who may not have serviced any customers.

Note you want the number of shipments, not the sum of shipment quantity. For example, if you have one shipment of 10 units, and another shipment of 20 units, our number of shipments here is 2.

Sort the list descending on number of shipments, and then on employee id. If an employee has not serviced any customers, display that employee at the top.

What is the first name of the very first employee you display?  (Just type the first name here.)

 

How many shipments did employee Sophia Moore have to Lake Erie Guitars?

Part 2 – Construct your Warehouse SQL

Part 2 – Construct your Warehouse SQL statements

 

This is where you start to turn things in.  To turn in your assignment, delete the preceding pages and start with this one.   Make sure to put your name up top. 

 

Construct SQL to answer each of the following questions.  For each query, paste your SQL code below, and also paste a screenshot of the first 10 or so rows the query gives you. 

 

Give an answer to the question based only on what you see in your MySQL database.  (Do not use Excel or other tools to answer these questions; since we are trying to learn MySQL here, you should do these exercises in MySQL.)

 

You will eventually submit this document as part of your week’s homework. 

 

After you have completed your first draft of this document, you will use the online quiz to verify your answers.   The online quiz uses the same numbering system given here, so you can quickly find the question you need. 

 

You are welcome to update your homework document with results from the online quiz, and submit the homework document after you’ve checked your homework online.

 

 

1.       [SQL Week 2 Question 200-501] For every shipment in the shipment table, you want to know its shipment details, the customer information, and the employee information. 

a.       Include exactly and only all the records for which a shipment ID exists.  

b.       Sort it ascending by Scantag. 

c.       Your output should look a little like this.  Note the “shipment information” will be in the form of several distinct columns.  (Hint:  look up the “ Select * ” command to select several columns at once.)

Assignment 2.5A In this assignment, we walk you

Assignment 2.5A

 

In this assignment, we walk you through joins which use more than two tables. 

 

Here’s what you are going to do for this assignment. 

·         Review this document.  There are several parts to this document.

o   Part 1 is instructions only.  There is nothing to turn in, but it contains important information.

o   Part 2 of this document is called the TURN IN part.  This contains something you should turn in for this assignment.

·         Go through this document and write SQL to answer all the questions listed below.  As part of your SQL, you will capture screenshots and paste them where indicated.

·         Refer to this document as you complete the online quiz which verifies your homework.

·         You are welcome to use the quiz results to update your homework file.

·         When you have completed the online quiz, submit the TURN IN portion of this document in the Assignment dropbox.

·         Remember, you can always reach out for help to your FA or instructor if your SQL is not behaving for you.

 

·         Your completed deliverables for this assignment are:

o   The TURN IN section of this document, submitted to the LEO dropbox

o   The completed online quiz results

 

·         There is no deliverable of a SQL script for this assignment.  You are welcome to create one for your own records, but the TURN IN section of this document will suffice for your faculty.

 

·         And, you probably already know this by now, but you can always reach out to your FA for assistance.

 

 

Purpose:  get more practice with multi-table SQL queries.  We will practice

·         Complex joins

·         LEFT and FULL joins

·         Order by and Group by

 

 

Part 0 – Get into your Folder

 

We will continue to work in the “Week2” folder inside your “DATA620” folder.   Download everything into this folder and run it from there.

 

 

Part 1 – Fire up the Warehouse database

 

1.       Go ahead and fire up MySQL Workbench and connect to your Azure MySQL database.

2.       Download and run the following scripts.  They will install a new database schema called “warehouse” which contains information about your customers, your products, your employees, and your shipments. 

a.       Warehouse_setup.sql – this will create a database schema called “warehouse”

b.       Warehouse_insert.sql – this will populate your database with information about your customers, products, employees, and shipments.  (Note there may be a numeric suffix on the end of your sql, so its name may be ‘warehouse_insert_v04.sql’ for example.  The information in your database may or may not be exactly the same as in this example.  That’s OK.)

c.       You can make sure that all tables are properly populated by executing;

SELECT * FROM warehouse.<replace-table-name>;

 

Where <replace-table-name> is in {customer, employee, product, shipment}

 

d.       The insert SQL also contains one query at its bottom, which should give you a list of the company names and shipments.   The first one should be from ABC Incorporated, with an idShipment of 1200 and a Quantity of 9.

 

 

3.       Let’s reverse engineer this database to see what the EER looks like. 

a.       Remember how?  Database -> Reverse Engineer and then click “next” until it gives you the EER.  I needed to drag my tables a little bit apart so I could see them all. 

b.       You can export your diagram using File -> Export -> Export as PNG.  You can also grab a screenshot. 

 

c.       Verify you can see one primary key for each table. The primary key is denoted by a golden key icon.

d.       Verify you understand the relationships.  You should be able to see that a customer, product, and employee can exist independently. 

e.       You should also be able to see that a shipment ties a quantity ordered with the customer who ordered it, the product which was ordered, and the employee who fulfilled the order.    A shipment also contains a Scantag and a Reference Number, two internal notations the company sometimes uses.

 

 

 

4.       You may want to refresh your memory about how to do three-table joins.  In the WWW3 Schools SQL instructions, you can see the “SQL Inner Join” on the left menu, and halfway down that page there’s a note about how to JOIN three tables. 

5.       There is nothing to turn in from this part.

This assignment covers how to import data from Excel to MySQL, and how to export data from MySQL to Excel.

 

If you have a Mac, please see the last page (Appendix) for some helpful notes.

Reading:

?        MySQL Reference Manual, Section 13.2.9.1 – how to use the SELECT INTO command

 

This document contains an EXAMPLE of each type of operation; you do not need to turn in anything related to the examples. The basic logic path of this assignment is:

1.       Get your SQL up and running, and connected to the Cloud.

2.       Prepare your Excel file into a .csv for import and get it in the right spot.

3.       Import: Using Table Import Wizard

4.       Export: One option presented; this sends your output file to a designated folder on your local machine.

After the examples, there is an assignment. Your deliverable here is marked with TURN IN and consists of:

?        An SQL script

?        An output .csv file

 

I have chosen to err on the side of lavish documentation here, so if you’re feeling Spartan instead, you are welcome to skip straight to the assignment on the last few pages. But if you’d like an extravagant collection of screenshots with commentary, turn straight to page 2.

 

EXAMPLE of an IMPORT:

 

Raw data stored in xls/xlsx files can be imported into MySQL databases easily. The following tutorial will demonstrate the data import process. This tutorial demonstrates a simple 50 row Excel sheet import process:

Please be aware of the following facts before you attempt the import process:

?       You can only export one worksheet at a time to the MySQL database that you have created. Exporting is fast and easy provided they are in compatible formats and within a reasonable file size.

 

?       The Excel worksheet should be clean (free of fancy formatting such as images, colors, wrap text and fancy fonts) before exporting. (The example we are doing here is well?behaved, but if you are trying to import other data from the wild, you may need to tame it a bit before doing the import.)

 

Get your Excel file prepared for upload to MySQL:

1.       Make yourself a “Week 4” folder. Pay attention to whether you put a space between the “Week” and the “4” – I suggest you put a space there because I did, and then your filename/paths will match these directions. (If the script calls for “Week 4”, and you have “Week4” or “Week_4”, the computer won’t find it.)

WK 4 – DATA 620 Discussion 4.1B - Data Quality and Governance   Do this as a GROUP ASSIGNMENT. (Once your group has submitted, you should have access to this thread.  If you don't, go ahead and submit a little something like 'Please disregard - Bobby from Group 9 posting so I can see responses.') This assignment covers data quality and data governance. Have your primary posting (the response to the boss) completed by Monday midnight, and have all your responses to classmates completed by Tuesday evening. Reading:  Data Quality  Inmon and Linstedt, Chapter 5.5 (Data Governance) Schwartzrock, Todd, "Chrysler's Data Quality Management Case Study," https://www.youtube.com/watch?v=N78lHpiCD0k (10 minutes) Edureka, "Data Quality Concepts | Data Quality Tutorial | Data Warehousing Tutorial," https://youtu.be/HWaBdqmTqEA (25 minutes) Accenture, "Data Quality Matters - Tech Vision 2018 Trend," https://youtu.be/abNDyLt8ilU (25 minutes) Data Governance and Stewardship (On this webpage, there is a button to download the pdf document) Watch the videos above and read Chapter 5.5 in Inmon and Linstedt.  Assume you work at XYZ Automotive, a competitor of Chrysler, and your boss has written you the following email: “Hi,  Everybody’s talking about data quality these days, but I’m not sure it’s actually worth the expense.  I’ve got three issues here and I want you to enlighten me.  First, I’m not really sure what data quality means – I know it means we spell the customer’s name right, but what else does it mean beyond writing down who bought what car when?  In other words, can you define data integrity for me?  Second, what exactly is data governance and how would it apply to our company?  And last, I need to make a business decision.  We’re considering having a consulting firm do an engagement which it says will radically improve the quality of our data.  What business advantages has Chrysler actually seen from its data quality initiative?  What advantages would you think we could get by doing our own?” Compose an email to answer your boss.  Please paste the text of the email within the discussion forum; do *not* put your email as an attachment.  Make it easy for us to respond!   Include in your submission your group name; for example, if my group is Group X, I might title mine, "Group X says we absolutely need better data governance." Choose two other submissions to respond to.  In your response, include three stars (three things they did well), plus one wish (constructive criticism.)  The responses to classmates may or may not come from the same person who did the initial posting.  Again, make sure it's easy to tell which group is responding; title it something like "Group X responds to Group Y." A successful submission will Contain approximately 300-500 words, plus a bibliography Be as formal (or informal) as you would take in a tone with an email to your boss – the only difference here would be that you do need APA citations and a bibliography. Pass a reference citation check for plagiarism – cite all your sources Define data quality and cite your sources.  You may use sources outside of the Chrysler and Global Data Store assigned sources, but you must convince me you have watched those two sources as well. Define data governance and cite your sources.  Again, you may use sources outside of Inmon and Linstedt, but you must convince me you have understood Chapter 5.5 in our textbook. Be as specific as you can about the business advantages for Chrysler from better data quality.  List (or estimate) dollars and any other performance metrics you can find.  (You are expected to be able to answer this using mostly just the Chrysler video; you are welcome do to brief Internet searches – and cite your sources - if you want to look up a fact or two, but this is *not* a research question.) Give good feedback to classmates on their postings.

WK 4 – DATA 620 Discussion 4.1C

WK 4 – DATA 620 Discussion 4.1C - Star Schema vs. Relational Databases

 

Do this as a GROUP ASSIGNMENT.

(Once your group has submitted, you should have access to this thread.  If you don't, go ahead and submit a little something like 'Please disregard - Bobby from Group 9 posting so I can see responses.')

This assignment covers the star schema vs. relational database schema.

Have your primary posting (the response to the boss) completed by Monday midnight, and have all your responses to classmates completed by Tuesday evening.

Reading:  Database schematics

This is not required reading, but it may be helpful:  past students have also found useful information on the James Serra blog posting about data warehouse architecture.

Your boss is at it again.  You are still working at XYZ Automotive, which is still a competitor of Chrysler, and your boss has written you the following email:

“Hi, 

So I’ve done a little research on star schema vs. relational databases, and I’m just plain old confused.  I’ve read the materials above, and Section 3.4 in the Inmon/Linstedt book, and I’m wondering if you could define the relational database model, define the star schema model, and tell me which one we need to use.  In plain old English.”

Compose an email to answer your boss.  Please paste the text of the email within the discussion forum; do *not* put your email as an attachment.  Make it easy for us to respond!  Include in your submission your group name; for example, if my Group is X, I might title mine, "Group X recommends the star schema"

Choose two other submissions to respond to.  In your response, include three stars (three things they did well), plus one wish (constructive criticism.)  The responses to others may or may not be from the same person who posted the initial submission.

A successful submission will

  • Contain approximately 300-500 words, plus a bibliography
  • Be as formal (or informal) as you would take in a tone with an email to your boss – the only difference here would be that you do need APA citations and a bibliography.
  • Pass a reference citation check for plagiarism – cite all your sources
  • Define the star schema database and cite your sources.  (Inmon and Linstedt in Chapter 3.4 refer to the star schema as a ‘snowflake’ schema.  Same thing.)  You may use sources outside of the Nagesh and Inmon/Linstedt assigned sources, but you must convince me you have understood those two sources as well.
  • Define the relational database model.  Again, you may do outside research, but you must convince me you have understood these materials.
  • Make a recommendation for which one the boss should get implemented at XYZ Automotive.  You are encouraged to clarify your recommendations – i.e. which conditions or in which situation would a star make more sense? 
  • Give helpful feedback to your classmates.

Investing $1,500,000 in TQM's Channel Support Systems

Investing $1,500,000 in TQM's Channel Support Systems initiative will at a minimum increase demand for your products 1.7% in this and in all future rounds. (Refer to the TQM Initiative worksheet in the CompXM Decisions menu.) Looking at the Round 0 Inquirer for Andrews, last year's sales were $163,290,917. Assuming similar sales next year, the 1.7% increase in demand will provide $2,775,946 of additional revenue.   With the overall contribution margin of 34.1%, after direct costs this revenue will add $946,598 to the bottom line. For simplicity, assume that the demand increase and margins will remain at last year's levels. How long will it take to achieve payback on the initial $1,500,000 TQM investment, rounded to the nearest month?

Investing $1,500,000 in TQM's Channel Support Systems

Investing $1,500,000 in TQM's Channel Support Systems initiative will at a minimum increase demand for your products 1.7% in this and in all future rounds. (Refer to the TQM Initiative worksheet in the CompXM Decisions menu.) Looking at the Round 0 Inquirer for Andrews, last year's sales were $163,290,917. Assuming similar sales next year, the 1.7% increase in demand will provide $2,775,946 of additional revenue.   With the overall contribution margin of 34.1%, after direct costs this revenue will add $946,598 to the bottom line. For simplicity, assume that the demand increase and margins will remain at last year's levels. How long will it take to achieve payback on the initial $1,500,000 TQM investment, rounded to the nearest month?
