Draw an ERD for the following scenario: A department employs many employees, but each employee is employed by one department. Each employee has the following characteristics: emp_Num, emp_FName, empLName, empAdress. Each department has a code and a name. Some employees, known as “rovers,” are not assigned to any department. A division operates many departments, but each department is operated by one division. Each division has a code and a name. An employee may be assigned many projects, and a project may have many employees assigned to it. Each project has a code and a name. An assignment is characterized by a date and number of hours. A project must have at least one employee assigned to it. One of the employees manages each department, and each department is managed by only one employee. One of the employees runs each division, and each division is run by only one employee.

Swing Jazz Club ERD Problem Follow the Simple Procedure for ERD diagramming to design an ERD using the following user provided information. Remember the ERD will eventually turn into the design for a database from a top down view. Make sure you resolve any many to many conflicts. Label an identifier or primary key and all pertinent attributes given. If an attribute is not readily apparent from the user information, then make one up that makes sense for the particular entity. Therefore, all entities should end up with at least an identifier and another attribute that makes sense. You may use any of the approaches shown by the book, though the ER-Model and Crow’s foot are the most common. Make sure you show entities, relationships, cardinality, and optionality.
