I know you're in Michigan but if you can spare some time to hang out with some douchebags we'd love it. And congrats on the beautiful girlfriend and upcoming Filthy-Baby-J :) Nice, Niki looks better pregnant in a bikini than I do un-preggers :(

Must've been taken with your teeny little camera, seeing as how I still have your SLR. That is a *beautiful* baby belly.

cow (purpose) -> farm_animal (name, sound, leg_count)

Concrete Inheritance is used primarily for different entities of the same parent class example 1: types of 'people': user, agent, admin, supplier contact, customer contact, employee example 2: options (name, value): gender, phone-type, account types, dept codes Agree with Kev.

This will hopefully come in real handy on a project I'm working on where there's a public timeline of actions and when I query get the last 20 actions I only need to query one table and every entry in the timeline can have it's own individual ID The key advantage I found with using the column aggregation is that you can use dql to query the parent table and then get back the child objects.

I agree with the conclusion that concrete inheritance mode is the best one among the three. But the mileage may vary depending on the specific need and circumstances. I wish to add the issue with concrete inheritance which nini has just raised. Even the concrete inheritance mode is not complete enough for the needs of true object-oriented logic: although there exists a top-level table farm_animal, this table will always be empty. The dogs, cows and chicken are exclusively stored in their respective tables, and none of them at all in the base class table. This arrangement is unlucky, as it inhibits browsing and quering through _all_ FarmAnimals, no matter which their (sub-)class is. So e.g. it is not possible to search for an animal called "Rosa", without knowing whether Rosa is a dog or a cow. And more importantly, as nini is stating, you can't setup an association between FarmAnimal and e.g. Farm ("a farm has zero, one or more animals"). Doctrine 2.0 may sometimes offer true full inheritance functionality by introducing "table inheritance". That mode should avoid any redundancy (no same field exists in multiple tables) and then have the base class' table store its part of each object, now allowing queries to be made on FarmAnimal level. Good post!
