Consider the following requirements for a University database that is used to keep records of professors, senior students and senior projects. In the university, each senior project is identified by a unique project number, and has a name, and the main professor managing the project. Each project also has a potential span, which is recorded as the project potential starting and ending dates. A project may also have co-professor(s) working on the project other than the main professor managing the project. Each professor has a CPR, name, rank, and research specialties. A university professor can manage and/ or work on multiple projects. In addition, the database should keep track of all senior students' records. Each senior student has a CPR, ID, name, age, and date of birth. As soon as a senior student works on a senior project, the starting date is recorded. A senior student can work on only one project but a project could have up to three senior students. A senior student could be assigned to another more senior student (known as student advisor) for general advises in projects and courses in the university. Design an ERD for this application. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.

Transcribed Image Text:Consider the following requirements for a University database that is used to keep
records of professors, senior students and senior projects. In the university, each
senior project is identified by a unique project number, and has a name, and the
main professor managing the project. Each project also has a potential span, which
is recorded as the project potential starting and ending dates. A project may also
have co-professor(s) working on the project other than the main professor
managing the project. Each professor has a CPR, name, rank, and research
specialties. A university professor can manage and/ or work on multiple projects.
In addition, the database should keep track of all senior students' records. Each
senior student has a CPR, ID, name, age, and date of birth. As soon as a senior
student works on a senior project, the starting date is recorded. A senior student
can work on only one project but a project could have up to three senior students.
A senior student could be assigned to another more senior student (known as
student advisor) for general advises in projects and courses in the university.
Design an ERD for this application. Note any unspecified requirements, and make
