Why no 1to1 relationships?

Subject: Why no 1to1 relationships?

I've decided to fully EOize my app to replace my current use of flat files, mainly to better deal with concurrency issues. In creating my analogous tables, I found that there's no way to specify a "1 to 1" relationship between tables using the Entity Modeler tool. Is there a specific reason for this? Or is it just figured that you might as well make it one to many anyway even if it is just one to one?

If you're wondering why I want to do this, it's to hopefully reduce conflicts of multiple people updating the same record in a table. Is that generally a good reason to split 1 to 1 data into two tables?

Thanks,
Jeff
