A model is an abstraction of the information objects and the functions
Models are buuilt for a variety of Designs.
A good design helps in achieving optimum performance.

Topology option depends on:
1 - Application
2 - Size of Organisation
3 - Topology and Distributed System
4 - Location of various data servers
