A Data Warehouse for a University consists of four dimensions: students, courses, semesters, and lecturers. There are two measures: 'sum' and 'average'. In the lowest conceptual part, for example the combination of courses, semester, and lecturers, for certain students, the 'average score' number contains the actual course of the student. At a higher conceptual level, the 'mean value' contains the average value for the combination. Draw a diagram for the Data Warehouse above using Snowflake Schema.
