But, I don't know how to fix IE! :-) Which is why I had not reported
this as a WO bug: it isn't. But I will happily file this as an

Database Design - Multiple locations
I have a database design question. I am posting it to the WebObjects list because I am building a WebObjects app and want a solution that works well for EOF. I have a table of data that has to have a location associated with it. Unfortunately the level of the location is not constant. The data can be associated with a Country, Region, State, Metro Area, County or City. Each of those levels is its own table with relationships pointing to the related locations. i.e. a State knows which Region it belongs to and which Metro Areas belong to it. I have been unable to come up with a design that seems elegant. I have thought of having 6 separate relationships to each of the location levels, but it seems to duplicate data and the data could get out of sync if a state is moved to a different region or a City is moved to a different county. Has anyone had a situation like this and come up with a good solution? Thanks, Frank Cobia ___ Do not post admin requests to the list. They will be ignored.

Re: Database Design - Multiple locations
Does your data haphazardly point to any location? Or does it point always to city (the most discreet) which is hierarchical down from Country? If that is the case just point it to city and you will have access to all the other locations as they would all be joined in to-one relationship up the tree. Otherwise, maybe have an intermediary object that has a type attribute. HTH James Cicenia On Apr 20, 2008, at 8:15 PM, Mr. Frank Cobia wrote: I have a database design question.
