Consider the following information about a university database:• Professors have an SSN, a name, an age, a rank, and a research specialty.• Projects have a project number, a sponsor name, a starting date, an ending date, and a budget.• Graduate students have SSN, a name, an age, and a degree program (e.g., M.S. or Ph.D.).• Each project is managed by one professor (known as the project’s principal investigator).• Each project is worked on by one or more professors (known as the project’s coinvestigators).• Professors can manage and/or work on multiple projects.• Each project is worked on by one or more graduate students (known as the project’s research assistants).• When graduate students work on a project, a professor must supervise their work on the project. Graduate students can work on multiple projects, in which case they will have a (potentially different) supervisor for each one.• Departments have a department number, a department name, and a main office.• Departments have a professor (known as the chairman) who runs the department.• Professors work in one or more departments, and for each department that they work in, a time percentage is associated with their job.• Graduate students have one major department in which they are working on their degree.Create an ER/EER diagram that fulfils the above requirements and motivate your suggestions. The exercise will be assessed both according to correct ER/EER syntax and whether you have made a good design. 2:36DoneAssignment3 2ER/EER ModellingConsider the following information about a universitydatabase:• Professors have an SSN, a name, an age, a rank, anda research specialty.• Projects have a project number, a sponsor name, astarting date, an ending date, and a budget.• Graduate students have SSN, a name, an age, and adegree program (e.g., M.S. or Ph.D.).• Each project is managed by one professor (known asthe project's principal investigator).• Each project is worked on by one or more professors(known as the project's coinvestigators).• Professors can manage and/or work on multipleprojects.• Each project is worked on by one or more graduatestudents (known as the project's research assistants).When graduate students work on a project, aprofessor must supervise their work on the project.Graduate students can work on multiple projects, inwhich case they will have a (potentially different)supervisor for each one.Departments have a department number, adepartment name, and a main office.Departments have a professor (known as thechairman) who runs the department.• Professors work in one or more departments, and foreach department that they work in, apercentage is associated with their job.• Graduate students have one major department inwhich they are working on their degree.Create an ER/EER diagram that fulfils the aboverequirements and motivate your suggestions.
