The system should enable the staff of each academic department to examine the courses offered by their department, add and remov

e courses, and change the information about them (e.g., the maximum number of students permitted). It should permit students to examine currently available courses, add and drop courses to and from their schedules, and examine the courses for which they are enrolled. Department staff should be able to print a variety of reports about the courses and the students enrolled in them. The system should ensure that no student takes too many courses and that students who have any unpaid fees are not permitted to register. (Assume that a fees data store is maintained by the university’s financial office, which the registration system accesses but does not change).
Required:
Draw an Interface Structure Diagram (ISD) for the university registration system.

Simora [160]

Answer:

The owls population increased by 13 in one year

Explanation:

The given data on the owl population are as follows;

The number of new owls born = 20 (positive increase in population)

The number of owls that die = 10 (negative decrease in population)

The number of owls that enter the forest = 5 (positive increase in population)

The number of owls that left the forest = 2 (negative decrease in population)

Let 'w' represent the number of new owls born, let 'x' represent the number of  owls that die, let 'y' represent the number of owls that enter the forest and let 'z' represent the number of owls that left the forest, we get;

The change in population, ΔP = w - x + y - z

By plugging in the values, we get;

ΔP = 20 - 10 + 5 - 2 = 13

The change in the population of owls in one year is an increase in 13 owls.
