| Abstract(in English) | For a complex object model,a form of range restriction,called specialization constraint(SC),has been studied.On the other hand, very few models have been proposed that support selective inheritance.In this paper,the following consideration is taken into a complex object model which supports selective inheritance. It is shown that it is decidable in polynomial time whether or not a given database schema is well-formed.Sound and complete axiomatization for SCs are given.Let Σ be a set of SCs.A polynomia l time algorithm is given that decides whether or not a given SC is a logical consequence of Σ.Finally,another polynomial time algo rithm is given,which decides whether or not there exists a database that contains the path. |
