. Consider the following information about a university database: Professors have an SSN, a name, a rank, and a research specialty. Projects are identified by a project number, more than one sponsor name (e.g., NSF), a starting date, an ending date, and a budget. Graduate students have an SSN, a name, and a current degree program (e.g., M.S.or Ph.D.). Each project is managed by one professor, each project is worked on by one or more professors and each project is worked on by one or more graduate students. When graduate students work on a project, a professor must supervise their work on the project. Graduate students can work on multiple projects. Departments have a department number, a department name, and a main office. Departments have a professor (known as the chairman) who runs the department Professor works in one or more departments and for each department that they work in, a time percentage is associated with their job.
