To consider the following case and draw the ER model

Case background

International Office (IO) needs a database to assist simple and fast data entry and print reports. The key information is collected from the students during their enrolment. In order to make this process fast and easy for the students, the data entry has to be as capable as possible. If the data entry takes too long the student may become unconcerned in joining the university. The director at IO requires reporting features to facilitate them to help with rostering, roles and membership email lists. Some such reports include: organising a roster for the volunteers, finding all of the people interested in organizing a social function, printing a list of contacts etc.

IO Background

IO, as the acronym recommends, is planned to help the students by providing a friendly place where they can meet other part-time or full-time students. Facilities and services include: a pool table, tea and coffee, a kitchen, few games and a number of social events for the students to attend. If the students have an hour break among classes then they can come to the IO lounge and relax on the couches, play pool, chat over a coffee and so on. In regard for these facilities to stay hygienic and well maintained, certain rosters are set up for the student members. These rosters are generated from the database of students wishing to volunteer for a particular job or jobs. From time to time notices and documents are sent out to the members to remind them of their allocated duties and to inform them of upcoming events and activities.

A range of jobs that need to be accomplished at the IO lounge require volunteers to complete certain tasks like, washing windows, vacuuming floors, mopping etc, and these may need to be done at certain times of the day and/or week. IO would like the database to keep track of the tasks required in each job. They would also like a record of who does what job on what day and whether it was completed or not. Moreover, University faculties, schools and the course, that students are in, are very significant to IO so that they can categorize people into study groups and for mentoring purposes. A new member can be introduced to people doing the same course or in the same faculty or school. IO would like the database entry screens to be designed for simple and easy navigation of information in the database. The first screen should contain contact details. The second screen should be about what IO can do for them, and the third screen should be what the student can do for IO.

How IO process works

At the time of enrolment, the interested students fill out a form giving their contact details to IO. They also indicate whether they would like to help out in the duties involved within the university. The databases are updated with new members every year. This guarantees that the current database is up-to-date. Reports are then generated from the database that helps the IO team synchronize and locate volunteers.

The database reports make it easy and simple to generate rosters, mailing lists, organise social functions and meet nutritional needs of the students. IO would like the make the data entry as simple and easy as possible for the student enrolment. They would like the reports to be easy to produce. They also recommended that each school in the university should be linked to itsassociated Faculty. So that somebody cannot enter Faculty of Information Technology and School of Law as this is incorrect.
