1. The Hudson Engineering Group (HEG) has contacted you to create a database for its training program. The HEG has several instructors, and offers advanced technology courses, each of which may be taught several times a year. Each offering is taught by one instructor, and can have up to 30 students. Instructors are capable of teaching many different courses. Draw an entity-relationship diagram for HEG (in 3NF!).
