I totally agree with your message, but please slow down when you write. Maybe make an outline first, and have a few people edit it for you. You clearly have some good points to get across. I'd like to see you express them effectively.

One problem in particular is that you present your 'MUCK' table (thing) later in the article than you do the properly normalized tables (EmployeeStatusCode, CustomerStatusCode, etc). This is confusing; think about the flow of the article: Introduce problem (MUCK); show example of problem (MUCK tables); introduce solution (normalization); show examples of normalization (normalized tables)...

Again, good effort; execution just needs a bit of work.
