In Section 16.3.2 we pointed out that in a multidatabase system, data could not be communicated directly from one database site to another and that even indirect communication was difficult since a query site cannot send data to a database site. However, the following “end run” might be considered for computing a semi-join. The query site, A, executes a SELECT statement at the first database site, B, which returns the projection, P, used in computing the semi-join. Site A then uses the projection to dynamically construct another SELECT statement whose result set is the semi-join. Using Example 16.3.1 on page 699 of Section 16.3.1 involving tables Student and Transcript, give the two queries. Under what circumstances could such an approach be considered?
