ERD Table and Field Questions !ERD


My question is two-fold.  

First, this is my first design and I am using the Mere Mortals book to help me.  He states, "...each table represents a single, specific subject."  So should I combine the Statistics table and Designer tables into the Project table since the subject is Project?

Secondly, the two fields of WhyClientChoseUs and ClientLossReason are opposed to one another and only one of these two fields would be filled out. Is that OK?  And should this go in the Project table and not the Client table?

Thanks in advance.
According to the annotations in your ERD diagram, I understand that:


A Client may have many Projects
A Project may have many Designers


If that is true, then these 2 tables should not be consolidated.

Likewise, depending on your definition of WhyClientChoseUs and ClientLossReason, there are reasons to keep both.  (E.g. you may have a reason WhyClientChoseUs and later need to add the ClientLossReason.  Not uncommon on big projects.)

But, because the client may continue with one project but abandon another, the Project may be a better place to keep that information.

But answers to these kinds of question do depend on your definitions.
