What is Database Management System?

The collection of data is known as database.

Database Management System (DBMS) is a collection of two things: 
  1. The interrelated data, and 
  2. A set of programs to access those data.

Database system must also ensure the safety of information that is being stored, despite the system crash or an unauthorized access.

a. Construct an E-R diagram that models exams as entities, and uses a ternary relationship, for the above database.  b. Construct an alternative E-R diagram that uses only a binary relationship between students and course-offerings. Make sure that only one relationship exists between a particular student and course-offering pair, yet you can represent the marks that a student gets in different exams of a course offering. (a) (b)
