You are modeling the relationship of employees and managers in your organization. One possibility is to show a unary or recursive relationship on the EMPLOYEE entity. How would you model the cardinality of the unary relationship to indicate that an employee has one manager and a manager may have many employees? Draw the model to show that an employee must have a manager. Now draw the model to show that a manager must have at least one employee. What happens if a manager has only one employee assigned, and then that employee is reassigned? Draw the relationship with cardinalities to indicate that a manager may have no employees.
Your organization asks you to create a data model for employees participating in projects. One employee can participate in many projects. One project can have many employees assigned. Your stakeholders want to know the role of each employee on a project. Address the following questions in your paper:
Which type of entity will help you model this many-to-many relationship?
Is it possible for a project to have no employees assigned, and how would you model that possibility?
Is it possible for an employee to be unassigned to any project, and how would you model that possibility?

A Value Chain is a network of facilities and processes that describes the flow of goods, services, information, and financial transactions from suppliers through the facilities and processes that create goods and services and deliver them to customers. The Value Chain is an identification of where in the Supply Chain value is added and how it is added. This assignment requires students to develop a Value Chain and explain why/how each component of the chain adds value to the ultimate product or service. The Value Chain should be based on the same company that you based your Supply Chain on (ITP Company)- Inside the File
Students will develop a value chain based on the supply chain for the assigned product or company provided by the course instructor. Students should compute the value generated at each step. The value chain should include based on the students business plan, configurations of resources such as suppliers, factories, warehouses, distributors, technical support centers, engineering design and sales offices, and communication links. Students should show awareness of effective resource allocation and its ethical implications. Specific details for the assignment will be provided by the course instructor.
