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).
