I’ve used the product and found it to be very helpful. DB-Examiner found mistakes I’ve made on more than one occasion. Using the product has saved me lots of time and gives me additional confidence that my data model is correct.

Examiner is like a spellchecker that insures that your relational model conforms to relational theory. Examiner also looks for important  physical design problems such as logical foreign keys defined without an enforcing foreign key constraint or supporting index. Finally, Examiner is a great way to educate junior and midlevel database engineers on relational theory via the product extensive HELP facility.

I strongly suggest you download it and run it against your model and tell me what you think. This is a unique opportunity to make your job as a SQL Server professional easier and less stressful.
