Student(StudID,SName,SAddr)
Transcript(StudID,DeptCode,CrsNum,Semester,Grade)
(a) Write an SQL query that generates a table of the SNames of all students taking courses in the department with DeptCode ?CS?. (b) Give the ?naive? translation of your SQL query into the relational algebra (as given by the general translation of SQL to relational algebra.) (c) Assume that there is an index with search key DeptCode on the transcript table, and no other indexes. Describe carefully and completely how you would evaluate the above query in a most ecient way. Give a precise query plan and carefully describing each operation. (d) Give the relational algebra expression for this query that most closely corresponds to the way you chose (in the previous subproblem) to eciently evaluate this query.
