Student studies different Courses offered by College. Faculty teaches these Courses. In each semester one student can take more than one course and Faculty can teach more than one courses. Faculty members can teach in multiple courses. Each course can be taught by many faculty members or no one. Faculty members are also working on multiple research projects. These projects are funded by government and college. The details of the project are name, duration and area. One project can have more than one faculty member and one faculty member can work on more than one project. Based on the situation given above, draw a complete Entity Relationship Diagram using the Crow's Foot notation which includes: (6) (ii) All entities and attributes Relationships (iii) Connectivity and relationship participation Primary and foreign keys (iv)
