I'm trying to find the following
find every department that has a professor who taught all courses offred by that department.
Using relational algebra and then using SQL.
The schema is as follows:
Student(Id:Integer, Name:String, Address:String, Status:String)
Professor(Id:Integer, Name:String, DeptId:String)
Course(DeptId:String, CrsCode:String, CrsName:String, Descr:String)
Transcript(StudId:Integer, CrsCode:String, Semester:String, Grade:String)
Teaching(ProfId:Integer, CrsCode: String, Semester:String)

Any help would be much appreciated, I'm starting think that it is near impossible to represent this in a one line relational algebra formula.

Thanks!

Why has the continental 7's been imported into the UK? They, the continentals, 'bar' their 7's solely because their 'ones' have a downward 'tick' from the top of the number, which unless their 7's had a 'bar' on them they wouldn't be able to tell the difference. As we in the UK do not have this one 'tick' it is quite unecessary to 'bar' our 7's. Please stop putting a horizontal 'bar' on our UK 7's.

There is a group of balls, either red or blue. The number of red balls is not necessarily the same as blue balls.

We have 2 boxes, A and B. We are to assign the balls to the box. Each ball has a probability P that will be assigned to box A and 1-P to box B. This probability P varies for different balls.

After the assignment is done, we are to get a ball from the box A. What is probability that the ball I get is red (and similarly blue)?
