Answer 1

In a star schema for recording grades, there are four dimension tables: Course, Section, Student, and Grade. Each table has its own attributes that provide additional information.

Step-by-step explanation:

In this star schema design for recording grades, there are four dimension tables: Course, Section, Student, and Grade. Each dimension table has its own attributes that provide additional information. For example, the Course table might have attributes like course_id, course_name, and course_description.

The Section table might have attributes like section_id, section_name, and instructor_name. The Student table might have attributes like student_id, student_name, and enrollment_date. And finally, the Grade table might have attributes like student_id, section_id, and grade_value.

By linking these dimension tables together using foreign keys, you can create a comprehensive star schema that allows you to record and analyze grades for courses completed by students.
