Thanks to the previous posters. Secretly I'm pretty much in agreement with all of you that EAV in theory sounds good but the cost of just getting our development team to swallow the little red pill and jump down that rabbit hole and become 70% efficient and by the end have a 100% successful application is going to be nigh impossible. Our team is more comfortable with straight RDBs and MySQL so in my mind it would make sense to keep it simple and avoid the headache of trying to CRUD EAV across so many tables.
Right now the application doesn't need to be the most flexible forward thinking db schema out there as the application as of right now is only meant to service one state. But what if it becomes popular and opens up to 10 or 20 states? Our main concern is that how are we going to manage the details/rates of an Insurance Plan when 2 or more states have the same Carrier and Plan but the Rates are different based upon their attributes (Smoking, Number of Dependents, Single/Family, M/F, etc.). Has anybody dealt with a similar situation? We definitely don't want to end up with a database with an ungodly amount of fields with null values but would like it to have some flexibility for growth.
