Think about the system that handles student admissions at your university. The primary function of the system should be able to track a student from the request for information through the admissions process until the student is either admitted to the school or rejected. Create an package diagram of the HCI, PD, and Data Management layers. Be sure to include three classes in each layer from your structural analysis. In the HCI layer, be sure to include difference UIs that could be present in your system. In the Data layer, be sure to include different classes that would exist as objects during persistence of your data..
