I don't think you asked the right question. It seems you aren't asking
whether to use relational database systems but whether to normalize
your database or not.

The main motivation to normalize data is to preserve its integrity when
it is updated. A secondary reason is that normalization can help
performance by ensuring you aren't maintaining redundant data. Given
those factors you ought to have a good excuse if you don't normalize.

Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.
