1. Draw a network diagram that summarizes the systems described above; devices used by administrators, staff, instructors, and students; and the network connections among them. Assume that the current survey system will be replaced by a new Web-based system. Assume further that each existing CSU system is hosted on its own server.

Data Integration at Cooper State University Cooper State University (CSU) has used a paper-and-pencil survey system to gather student feedback on instructors and courses for over two decades. Paper forms are passed out to students during a class period near the end of the semester. Class information and survey questions are preprinted on the forms and empty circles are provided for each answer. Students fill in one of the circles for each question with a pencil. Written comments can be provided on the back of the form. The forms are delivered to a processing service in Nebraska, which scans the forms, summarizes the responses, and produces printed reports that are sent back to CSU along with the survey forms. The re- ports and survey forms are distributed to department chairs who review them and then distribute them to instructors. CSU wants to replace the existing system with a modern online survey system. Several vendors market such systems as SaaS Web-based applications. The systems all have similar data integration needs with existing CSU systems, including the following:
