Nico,
it is all up to you. In my programs, I reason that when the user closes a
form it represents to him a completed logical unit of work and that he
expects the work to be committed upon closing each form. Hence, I use one
transaction per form. But there's nothing wrong in having one transaction
in a datamodule and use it for all your forms.
