relation R (x,y) and relation S (z), Y and z have the same number of attributes, and the corresponding attributes are derived from the same domain. The quotient relationship R (x,y) ÷s (z) is a subset of relation R that is projected on the attribute X, and the Cartesian product of the subset and S (z) must be included in R (X,y), which is recorded as R÷s, and its calculated formula is: For example, the relationship between table 3-1 R and table 3-2 of the relationship S do division operations.
