Summary:Produce an ER Model for the following scenario (presented in Step 1 below) and business need, for the Pythagoras Math Academy.  Reference the attached video (Course Project Ph2 Video.mp4), for a full introduction and demonstration and expectations for this project.Deliverables:

  • ER Model for the scenario presented. 
  • You have the option to use MS Visio (if you have the software) to produce your ER Model.  
  • Alternatively, if you do not have MS Visio, you can use the ERD PLUS (Open source ER Modeling Software) and produce your ER Model. 

***The submission is a Word document with the ER Model diagram copied.  Do not send any type of image.  The submission must be the image copied into a Word document.  Please include a cover sheet with your full name, the class and  the university spelled correctly.  Please include any details necessary to describe the results. 
Required Software:

  • MS Visio by Microsoft OR
  • ERD PLUS, Open Source Offering. This offering is cloud-based, and you do not need to download any clients. You will need to create an account (username and password), link to this offering follows: https://erdplus.com 

Lab Steps:Step 1: Read and understand the Scenario and Business needs presented below. Define and document the ENTITIES, and RELATIONSHIPS, required to address the business needs. The nouns in the scenario below will give the ENTITIES that you will need. Finally, the verbs will describe the RELATIONSHIPS.Scenario and Business Need The Pythagoras Math Academy is in need to develop a database to keep track and control of his students, teachers, and classes offered. Teachers are able to teach multiple courses. But they are required to be certified on the course they are teaching. For example, only a group of teachers are certified to teach Algebra, and other Geometry. Students can take multiple courses. Courses are taught by teachers with the proper certification and have multiple certs as needed.  Courses are taught in one of the classrooms at one of the School’s several sites.Each classroom is optimized to serve the needs for a course (for example some courses might require computer labs and whiteboards). The school needs to keep track of the math courses delivered in each of the sites.Step 2: For this project, you are required to use MS Visio or ERD PLUS to produce the deliverables.If you are using MS Visio follow the steps below:

  • Reference the Course Project Ph2 VIDEO.mp4, for a short demonstration and tutorial of this tool, and project overview/ expectations.
  • Open MS Visio
  • Click on the Software Database Template in the main window
  • Select the Database Model Diagram Template to open a new file.
  • Save the File and ensure to have in your file name PROJECT2_LastName_FistInitial.

If you are using ERD PLUS.

  • Watch the recorded short tutorial for this tool. Reference the attached video as follows: Course Project Ph2 VIDEO.mp4.
  • From the ERP PLUS main interface, select DOCUMENTS –> NEW DIAGRAM (NAME YOUR DIAGRAM) –>ER DIAGRAM –> CREATE
  • Reference demonstration video for how to navigate tool, how to create entities, add attributes, relationships, and Cordiality. Demonstration video attached as follows: Course Project Ph2 VIDEO.mp4

Step 3: Define and Database ENTITIES

  • Add an entity for each Table you identified in the Scenario and Business Need.
  • You will use the MS Visio tool, or the ERD PLUS open source offering to complete this step.

Step 4: ADD the required ENTITY ATTRIBUTES  

  • Add the required Attributes for each Entity that you feel would help to define each Entity as needed.
  • Select one of the attributes to be PRIMARY KEY (PK)

Step 5: Define RELATIONSHIPS

  • Use the Crow’s Feet Notation.
  • Reference recorded demonstrations on how to use these notations, for MS Visio and ERD PLUS. Reference attached video as follows: Course Project Ph2 VIDEO.mp4
  • Drag and drop (draw) relationships between the entities you defined.
  • Connect the ends to the two entities for each relation.
  • Defined the Primary Key for the parent entity.

Step 6: Define CARDINALITY RELATIONSHIPSet the cardinality for each of your relationships defined in Step 5.  For MS Visio: select a relationship line in the drawing area that is connecting two entities. In the Database Properties window, select the miscellaneous category. Select the cardinality for the selected relationship.Step 7: Upload your Work 

  • Save the File and ensure to have in your file name PROJECT2_LastName_FistInitial. 

***The submission is a Word document with the ER Model diagram copied.  Do not send any type of image.  The submission must be the image copied into a Word document.  Please include a cover sheet with your full name, the class and  the university spelled correctly.  Please include any details necessary to describe the results. Rubric:

  • 10 points: ER Model (MS Visio OR ERD PLUS)
  • 10 points: Entities: Minimum of Three entities are represented
  • 10 points: Attributes: Minimum of Two attributes for each Entity. Most would require more than two attributes, and I am only requiring two per entity.
  • 10 points: Relationships: Minimum Three relationships are presented.
  • 10 points: Cardinality is defined and specific for each relationship with Crow’s foot notation.

assessment 4

 

You have just received two emails, one from your boss or supervisor and one from a coworker. The two emails address the same situation. A minor problem has occurred that you may be responsible for creating. Your boss/supervisor has asked you for a resolution to the problem. Your coworker, who has been affected by this problem, is angry with you and has written an inflammatory email accusing you of creating this problem on purpose.

  1. Using word, write an email as a reply to both of the emails that you have received. You should attempt to resolve the problem as efficiently as possible. Since your email will be received both by a supervisor and a coworker, consider all aspects of your communication including the formality of the language you use, grammar, and all aspects of formal communication. Your goal is to solve the problem and maintain your professionalism at the same time.
  2. On the same document, analyze the conflict that has happened. What was the cause of the conflict? How did you attempt to resolve the conflict? What did you need to address in terms of your supervisor’s concerns, and how were these different from your coworker’s concerns? Do you think your supervisor and coworker handled the conflict well in their emails to you? How effective are these emails?

1. Clayton Industries is planning its operations for next year, and Ronnie Clayton, the CEO, wants you to forecast the firm’s additional funds needed (AFN). The firm is operating at full capacity. Data for use in your forecast are shown below. Based on the AFN equation, what is the AFN for the coming year? Dollars are in millions. Last year’s sales = S0 $350 Last year’s accounts payable $40 Sales growth rate = g 30% Last year’s notes payable $50 Last year’s total assets = A0* $500 Last year’s accruals $30 Last year’s profit margin = PM 5% Target payout ratio 60% a. $102.8 b. $108.2 c. $113.9 d. $119.9 e. $125.9 

2. The ABC Corporation’s budgeted monthly sales are $4,000. In the first month, 40% of its customers pay and take the 3% discount. The remaining 60% pay in the month following the sale and don’t receive a discount. ABC’s bad debts are very small and are excluded from this analysis. Purchases for next month’s sales are constant each month at $2,000. Other payments for wages, rent, and taxes are constant at $500 per month. Construct a single month’s cash budget with the information given. What is the average cash gain or (loss) during a typical month for the ABC Corporation? (Points : 20)

This debt currently has a market value of $50 million. The balance sheet also shows that the company has 10 million shares of common stock, and the book value of the common equity (common stock plus retained earnings) is $65 million. The current stock price is $22.50 per share; stockholders’ required return, rs, is 14.00%; and the firm’s tax rate is 40%.
