So, it might be stating the obvious, but the primary consequence of using a non-transactional database such as MyISAM with WebObjects is that a failed EOEditingContext.saveChanges() will not be rolled back in the database which causes the unsaved EC changes to be actually *partially* saved resulting in inconsistent data, orphan records, relationships pointing to objects that don't exist, etc. and the most common error thrown by your app will become EOObjectNotAvailableException .... basically chaos and corrupt useless data because you shot yourself in the foot over and over :)
