Task 2: You are tasked with designing a database for a small school. The school has a limited number of teachers and students. Each teacher can teach multiple classes, and each class can have multiple students enrolled. The school wants to keep track of student grades and attendance. Using the information provided, create an Entity Relationship Diagram (ERD) to represent the database for the school. Be sure to identify the entities, attributes, and relationships in the scenario. The ERD should include the following entities: 1. Teacher 2. Class 3. Student 4. Enrollment 5. Attendance 6. Grade The attributes for each entity should include: 1. Teacher: teacher ID, first name, last name, email, and phone number. 2. Class: class ID, class name, room number, and time. 3. Student: student ID, first name, last name, date of birth, and grade level. 4. Enrollment: enrollment ID, student ID, class ID, and date enrolled. 5. Attendance: attendance ID, student ID, class ID, date, and whether the student was present or absent. 6. Grade: grade ID, student ID, class ID, date, and grade. The relationships between the entities should be: 1. One teacher can teach many classes. 2. One class can have many students. 3. One student can be enrolled in many classes. 4. One student can have many grades. 5. One student can have many attendance records for each class. Create the ERD and label the relationships using proper notation.
