Explain kernel approach, master approach and component approach? |
| |
- Kernel Approach : With the kernel approach, one universe contains the core components. These are the components common in all universes. The derived universes that you create
from this kernel universe contain these core components as well as their own specific components.
-
Master Approach : In this approach, one master universe holds all possible components. In the universes derived from this master, certain components are hidden; in other words, the components visible in the derived universes are a subset of the master universe.
- Component Approach : It involves merging two or more universes into one universe.
