• Message text: Création des 'index uniques' dans les tables cibles

A unique index ensures that the values of the index fields are unique.
If a target table has fewer or shorter fields than the source table or
if several source data records are mapped to the same target data
record when the data is mapped, these indexes ensure that only such a
data record is inserted.
It is better for the conversion speed if the target tables have as few
indexes as possible, since the indexes also have to be updated for each
insert or update operation. Therefore only the unique indexes are
created on the target table.
