Hi Jerome, Jerome Jacobsen wrote:
Good O/R tools provide object level transactions (aka Unit of work).Thanks very much. I will look into the book and SODA.However, I'm confused about the need for "an abtract transaction mechanism". Isn't JTA just that?
Jdo and ODMG Transactions are examples for this concept.
This concept is also covered in Fowlers book...
A Unit of work provides methods to register objects to it and to mark them for insert, update or delete.
Neither JDO nor ODMG Transaction are JTA transactions.
JTA is only used to integrates with app server managed datasources.
But this is quite a different conceptual level.
cheers,
Thomas
