C++ ODL/OML applications C++ ODL/OML some general points Outline Materi C++ ODL/OML applications C++ ODL/OML some general points

C++ ODL/OML applications Application Program C++ ODL Schema Object Database Declaration C++ program with OML Statements to manipulate the Object Database

C++ ODL/OML some general points An object oriented programming language ODL/OML binding can exploit the similarities between the underlying object models of the programming language and object database

C++ ODL/OML some general points An object oriented programming language provides an extensible type system-programmers can use the language to build new types to support specific application

C++ ODL/OML some general points Subtype/supertype relationship can be used to specialize conventional classes such that they also apply to the object data model Operation overloading can be used to provide additional definitions of conventional operators such that they can also apply to object data model elements

C++ ODL/OML some general points Access to the object data model languages can be provided through operations which take language expression as parameters and return the result of executing those expressions

C++ ODL/OML some general points Binding non object oriented programming language is more difficult, since there is less similarity between the underlying models In such cases, a loosely coupled binding is appropriate
