Divide

Understanding the concept:

The final relational operation is division. The relational divide operator (so called to distinguish it from mathematical division) returns the records in one recordset that have values that match all the corresponding values in the second recordset. For example, given a recordset that shows the categories of products purchased from each supplier, a relational division will produce a list of the suppliers that provide products in all categories.
