Select a topic or a business idea that relies on data storage and describe the entities and their relationships in the system. As an example, in a university student management system, there exists many entities including students, instructors, courses, sections, classrooms, departments, faculties, etc. Also, there are many relationships between these entities such as, students have insturctors as advisors, students enroll to courses, courses have sections, instructors work in departments etc. Moreover, consider what attributes should be stored about each of your entities? Students, for example, you may want to store social security number, name, address, phone numbers, birth date etc.

In a 1-2 page long text describe your system in a similar manner. A good proposal should have around 10 entities.
