We are looking to redesign our current system and a question popped up that I
am struggling with. (our business is auto insurance). Each vehicle on a
policy may have 1 or many coverages. For example, comprehensive, collision,
towing, property damage ... A couple of things: 1- some coverages will not
apply because they are state specific. 2 - some coverages will not be chosen
by the insured. Therefore, should I have a vehicle table with each coverage
and its premium as separate specific columns or should I add a coverage table
which will contain the coverage and premium. Under the later example if I have
10 coverages and I want to print them on the insured's declaration page don't I
have a possible performance problem with up to 10 i/os. Where as with the
first example I only have 1 read but possible space wastage. I know in 1st
normal form you should remove repeating groups, in my case is a coverage a
repeating group? Where do you draw the line? For example, clients may have
multiple phone numbers although I don't see many examples where the phone
numbers are split into another table. Please share any thoughts that may make
my decision easier. Thanks
Just an fyi, in our current design the coverages have been stored with the
vehicle.
