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...

1. The following set of brief scenarios describes the relationships between various entity classes. Draw the entity classes (only show entity name - no attributes or identifiers) and the relationship making sure to add notation (use any standard notation) that shows reasonable minimum and maximum cardinalities given the implied scenario. All scenarios will only have one relationship. The one relationship may be between a maximum of two entity classes (binary) or between an entity class and itself (recursive). If you...
