....are exploited. For reasoning at the logical level, we provide suitable techniques for query containment. In particular, we have developed an algorithm for deciding query containment with respect to a DM, which exploits a reduction to unsatisfiability in O QP , and which extends the one in [4, 5] to deal with both intramodel and intermodel assertions. Example. Figure 3 shows a DM, ZR , that represents an enterprise and two sources containing information about contracts between clients and departments for services, and about registration of clients at departments ....
