Consider the following schema:

Student(Student,Status)
Took(Student,Course)
Course(Course,Credits,Type)

In a Student relation, Status can be 'B' (beginner), 'CPR' (completed program requirements), and 'EG' (eligible to graduate). In a Course relation, Type can be 'C' (core course) or 'E' (elective course). Write the following row-level triggers which monitors insertions into Took: (a) When a 'CPR' student completes 130 credits, change the student's status to 'EG'. (b) When a beginner student completes all core ('C') courses plus 3 electives ('E'), change the status from 'B' to 'CPR'. Hint: The main thing in constructing such triggers is to rst gure out the conditions in the WHEN clause. This conditions are similar to complex WHERE clauses. For instance, (b) involves relational division (recall how to do such things with NOT EXISTS).
