Database design question?

Normalized databases have a design that reflects the true dependencies between tracked quantities, allowing quick updates to data with little risk of introducing inconsistencies. Instead of attempting to lump all information into one table, data is spread out logically into many tables. Normalizing the data is decomposing a single relation into a set of smaller relations which satisfy the constraints of the original relation. Redundancy can be solved by decomposing the tables. However certain new problems are caused by decomposition. Normalization helps us to make a conscious decision to avoid redundancy keeping the pros and cons in mind.
