Since the beginning of the operation driven by the new Ganil control system in February 1993, the relational database management system (RDBMS) has been more and more widely used. The most significant application relying on the RDBMS is the new beam parameters management which has been entirely redesigned. It has been operational since the end of the machine shutdown this year.

After a short recall of the use of Ingres inside the control system, the paper first explains how the parameters management is organized. Then it shows the database implementation and how the physical aspects of the Ganil tuning have been integrated in such an environment. Then the operator's view of the on line parameters management is given by some examples of the Motif programs used at the control level.

Lastly, the paper tries to draw some lessons by showing more generally what the use of the relational database brought in this context. Also future enhancements are presented.
