The table includes lesson ID, instrument ID, instructor ID, class level, class size, and monthly fee. The Class_Size records the maximum number of students within the lesson. All lessons are conducted on a weekly basis. The INSTRUMENT table records all instruments taught by the instructors at Gracie Music Learning Centre. This table contains instrument ID and description. In the ENROLLMENT table, Lesson_Day indicates the day when the lesson takes place (e.g. Monday, Tuesday, etc.), while Lesson_Time shows the lesson time. Start_Date in the ENROLLMENT table indicates the date when the enrollments start, which normally takes place on the first day of the month. As long as the enrollment is still active, the End_Date will be left null. The student details are recorded in the STUDENT table. Meanwhile, the parent details are recorded in the PARENT table. Note that each parent may have more than one child enrolled in Gracie Music Learning Centre. To further manage and develop the learning centre, the management of Gracie Music Learning Centre requires a Data Warehouse for analysis purposes.

Note that the management wants to be able to drill down some information in the Data Warehouse in these formats: ? For class size, the management wants to be able to drill down based on different class sizes, including individual, small class size (<= 3 students), medium class size (between 4 and 6 students, and big class (> 6 students). ? The lesson day is categorised into weekdays (Monday to Friday) and weekends (Saturday and Sunday).Develop a star schema named GracieMusic.
