The Pythagoras Math Academy is in need to develop a database to keep track and control of his students, teachers, and classes offered.

Teachers are able to teach multiple courses. But they are required to be certified on the course they are teaching. For example, only a group of teachers are certified to teach Algebra, and other Geometry.

Students can take multiple courses. Courses are taught by teachers with the proper certification and have multiple certs as needed. Courses are taught in one of the classrooms at one of the School$$s several sites.

Each classroom is optimized to serve the needs for a course $($for example some courses might require computer labs and whiteboards$).$ The school needs to keep track of the math courses delivered in each of the sites.
