Yes I did.
And as you said, its _more or less_ always a bad idea.
There is always those freaky project with extremely temporary data, low budget,

They are also good for defining delete rules, such as if this order is deleted,
make sure all orderrows are deleted too.
Correctly defined, they also speed up searching

Yes, No. Container-managed transactions are a big point of using EJB's.

I believe that the EJB container always relies on the
