Transient models:

It's based on the model TransientModel class. Moreover, the data stored in the database is temporary in this class which is periodically cleared data from the database table.

- Records in the wizard require only temporary storage, so they are deleted after some time from the database.

- Users have all permissions on wizard records, they don't require explicit access rights.

- Records in the wizard can refer through many2one fields or to regular records, but regular records cannot refer through many2one fields or to wizard records.
