Abstract: We present techniques for deriving types from existing object-oriented types using the relational algebraic projection operation and for inferring the methods 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 as before. Our results have applicability to... (Update)

...a lot of proposals for view systems in OODBMS. These approaches differ with respect to paradigms and aims. Some of the approaches [2, 1, 3, 11, 12] see views mainly as named query expressions and are primarily concerned with the integration of the type of query results into...
.... (the review can be found in [20] In the majority of approaches a view is defined as a virtual class derived from one or more classes [1] [3], 4] 5] 9] 10] 14] 17] 18] 19] called base classes. The approaches of MultiView [16] and eXor C [6] 7] consider a view...
