KONSEP DASAR PENDEKATAN OBJEK

1. UML (Unified Modelling Language)

• Metode pemodelan secara visual sebagai sarana untuk merancang dan atau membuat software berorientasi objek.

• Memandang sistem yang akan dikembangkan sebagai suatu kumpulan objek yang berkorespondensi dengan objek-objek dunia nyata (objek oriented)

• Combine the best of the best from

• Data Modeling (Entity Relationship Diagrams);

• Business Modeling (work flow); Object Modeling

• Component Modeling (development and reuse - middleware, COTS/GOTS/OSS/…:)

 2. UML DIAGRAM

• Structural diagrams

Used to describe the relation between classes

• Behavior diagrams

Used to describe the interaction between people (actors) and a use case (how the actors use the system)
