Question: Draw the ERD for the following situation. Show all entities, attributes, relationships, cardinalities, and modalities.
Each student (with attributes StudentID, StudentName, and StudentMajor) must be assigned one advisor (with attributes AdvisorID, AdvisorName, and AdvisorDepartment). Advisors may advise no students or may advise many students.
Each student must register for zero or many courses (with attributes CourseID, CourseTitle, and CourseCredits) with the help of one or more advisers. A course may have at least one student registered, and may have many students. Advisors may register zero or many students in courses.
We must keep track of students, courses, advisors, and the registrations for each semester (Hint: create an associative entity—Registration)

For this assignment, you should create an Entity Relationship Diagram (ERD) in Visio that shows a many-to-many relationship between DeVry University students and their classes. Since one student can have many classes and each class can have many students, you will need to create an associative entity to store the specific Student_Class data such as grade and attendance. Create the tables as well as the relationships. Don't forget to indicate the Primary Key and Foreign Key in each table. Tables...

ERD requirements: In your ERD*, you must include: • All entities and the relationships among them; • Reasonable attributes for each entity; • Notations of all PKs and FKs • Cardinalities for each relationship. ERD Cases: Draw an ERD for each of the following situations. (If you believe that you need to make additional assumptions, clearly state them for each situation.) Draw the same situation using the tool you have been told to use in the course. A laboratory has...

Use the following business rules to create a Crow's Foot ERD. Write all appropriate connectivities and cardinalities in the ERD.
Exercise 1: ERD Use the following business rules to create a Crow's Foot ERD. Write all appropriate connectivities and cardinalities in the ERD. A department employs many employees, but each employee is employed by only one department. Some employees, known as "rovers," are not assigned to any department. A division operates many departments, but each department is operated by only one division. An employee may be assigned many projects, and a project-may have many employees assigned to it. A project must have at least one employee...

In this phase of the project you will create an ERD based upon the following requirements and business rules. Limit your ERD to entities and relationships based on the business rules showed here. In other words, do not add realism to your design by expanding or refining the business rules. However, make sure you include all attributes needed that would permit the model to be successfully implemented, including all primary and foreign keys. 1. Trinity College (TC) is divided into...
