Deriving the Physical Design From the Logical Design

To derive the physical design from the logical design, you take the following major steps:

1. Allocate services to components. Derive components from the logical objects and determine whether each object is a user, business, or data service object.

2. Deploy components across the network. Assign the components to locations on the network.

3. Refine component packaging and distribution. Group components according to the system's needs.

4. Specify component interfaces. Define relations between components.

5. Validate the physical design. Make sure that each component corresponds to a service in the logical objects.
