Design an algorithm for incremental maintenance of a join index for a multiway star join.
What will be an ideal response?
With a star join of the form r cond1 r1cond2 r2 ...condn rn we maintain n binary join indices, for r cond1 r1, r cond2 r2, etc. The maintenance algorithm for these was described in Exercise 9.24.
