  Re: what we require for D.modelling?
Answer
# 1		 
Data modelling requires understanding of the requirements. 
In general the design of data model can be a snowflake 
(Highly normalized)  or star schema (partial or not 
normalized) which depends on whether you want optimal 
utilization of space (Use star schema) or you want a 
normalized data model easy to query and acess data (Use 
snow flake).
