Sandeep P. Dumbali,Pamela L. Wenzelmethods that are applicable to these types. Such type derivation occurs, for example, as a result of defining algebraic views over object types. We refactor the type hierarchy and place the derived types in the type hierarchy in such a way that the state and behavior of existing types remain exactly

We discuss in detail the translation function from GraphLog to each of LDL and CORAL, considering aggregation as well. We also present an example of using GraphLog and its environment Hy. in order to support software design understan

Without this restriction, query evaluation of general programs needs subsumption tests in order to terminate correctly, and subsumption tests are expensive..We study a class of programs that can handle terms with both variables and function symbols but for which subsumption tests are no

Its activation, which results in the creation of a virtual base, represents a context switch and provides a means for dealing with
