(Lanjutan bagian 3)
1
Learning Outcomes
Pada akhir pertemuan ini, diharapkan mahasiswa
akan mampu :
• Mahasiswa dapat Menjelaskan ikatan
antara programming language dengan
object database (C2)
• Mahasiswa dapat Menjelaskan pembuatan
object database application (C2)
2
Outline Materi
• C++ ODL/OML applications
• C++ ODL/OML some general points
3
C++ ODL/OML applications
C++ ODL/OML
Application Program
C++ ODL Schema
Object Database
Declaration
C++ program with OML
Statements to manipulate the
Object Database
4
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
5
C++ ODL/OML some general points
• An object oriented programming language
provides an extensible type systemprogrammers can use the language to
build new types to support specific
application
6
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
7
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
8
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
