I have the following ER Diagram for a bank database - customers may have several accounts, accounts may be held jointly by several customers, and each customer is associated with an account set and accounts are members of one or more account sets. What design rules are violated? What modifications should be made and why?

So far, a few flaws I'm not sure about are:

1) Redundant owner-address attribute in AcctSets Entity.

2) This ER does not include accounts with multiple owners with different addresses.

My Question is: How would I go about fixing these flaws and/or other flaws that I may be missing from my analysis? Thanks!
