Thanks Ramsey.
Yeah. I would really need a many-to-many relationship - which I was hoping to avoid. :-) I was wanting to just store and query "keywords" for my EO. A flattened many-to-many seems heavy to just associate string values. A good example would be a Contact entity where you maybe have a set of keywords like:
Christmas Card, Daily Mailer, Friend, Family, Special Offer, etc.
In the past, I've rolled a similar thing by writing the contents of an array to a comma-separated String - and back when reading from the database. Maybe the prototype 'stringArray' would be better?

On the UI side I would like to use checkboxes to select which categories to apply to an EO. Then, in the database have only those selections saved to the database.
