Hi Jeff,

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?


You can specify «1 to 1» relationship with Entity Modeler.

If the destination cannot be null, use the same id in the two tables.
-In Properties > Basic select : the cardinality «To One», your destination, and add your primary keys. -In Properties > Advanced select : for the source object, check Propagates primary key and Owns Destination (if the destination object cannot exist without an owner).

Good luck!

Jacky

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
