1. Technical Module C Object Modeling Objects Object – a valuable resource: Money (Account Receivable) Material (Product) Machines (Delivery Truck) Personnel (Employee) Environmental element of the firm (Customer) Described with data Includes the processes performed on it

2. UML Unified Modeling Language (UML) – a visual language used to document a system All SDLC methodologies All SDLC stages All applications All platforms

3. UML Structural diagrams (like snapshots) Use case Class Object Component (physical) Deployment (physical) Dynamic diagrams (like videos) Sequence Statechart Activity Collaboration

4. UML Rational Unified Process Stages of the object-oriented development methodology Inception Elaboration Construction Transition These are similar to the phased development methodology stages, and also incorporate the repetitive, prototyping action. Phased development can be followed using any modeling approach – including objects.
