Relational Dependencies: You make the Call....

[QUOTE="WWGD, post: 5477832, member: 69719"] Hi all, I am normalizing a database and I have the three fields: CompanyCity, CompanyState, CompanyZip It seems clear to me that there is a dependency : CompanyCity+ CompanyState --> CompanyZip But CompanyCity --> CompanyZip is not a dependency, since there are cities with the same name in different states. My colleague says this says both are wrong. Just want to have someone impartial clear up this disagreement. Thanks. [/QUOTE]
